AT – Automation Technology 3D Profilers – What makes them different? 

3D laser profiling is widely used in diverse industries and applications.  There are a number of mature offerings and periodic next generation innovations.  So what would it take to convince you to take a look at the value proposition for AT – Automation Technology’s C6 Series?  In particular the C6-3070, the fastest laser triangulation laser profiler on the market.

AT says that  “C6 Series is an Evolution.  C6-3070 is a Revolution”.   Let’s briefly review the principles of laser profile scanning, followed by what makes this particular product so compelling.

What are the distinguishing characteristics of each item labeled in the above diagram?

  • Target object: An item whose height variations we want to digitally map or profile
  • XYZ guide: The laser line paints the X dimension; each slice is in the Y dimension; height correlates to Z
  • Laser line projector: paints the X dimension across the target object
  • Objective lens: focuses reflected laser light
  • CMOS detector: array of pixel wells, or pixels, such that for each cycle, the electronic value of a pixel scales with the height value of the geometrically corresponding position on the target object
  • FPGA and I/O circuitry: provide the timing, the smarts, and the communications

The key to laser triangulation is that the triangulation angle varies in direct correlation with the height variances on the target object that reflects the projected laser light through the lens and onto the detector. It’s “just geometry” – though packaged of course efficiently into the embedded algorithms and precisely aligned optics.

The goal in 3D profile scanning is to build a 3D point cloud representing the height profile of the target object.

Speed and Resolution: 200kHz @ 3k resolution. That’s the fastest on the market. This is due to AT’s proprietary sensor WARP – Widely Advanced Rapid Profiling. How does it work?

The C6-3070 imager has on-board pre-processing. In particular, it detects the laser line on the imager, so that only the part of the image around the laser line is transferred to the FPGA for further processing. This massively reduces the volume of data needing to be transferred, but focusing on just the relevant immediate neighborhood around the laser line. Which means more cycles per second. Which is how 200kHz at 3k resolution is attained.

Modularity: When Henry Ford introduced the Model T, he is famously attributed to have said “You can have it any color you like, as long as it’s black.” Ford achieved economies of scale with a standardized product, and almost all manufacturers follow principles of standardization for the same reason.

But AT – Automation Technology’s C6 Series is modular by design – each component of an overall system offers standard options. There are no minimum order quantities, no special engineering charges, and lead times are short because the modular components are pre-stocked.

For example:

  • Laser options (blue, red laser class: 2M, 3R, 3B)
  • X-FOV (Field Of View) from 7mm to 1290 mm
  • Single or dual head sensors
  • Sensor parameters offer customizable Working Distance, Triangulation Angle, and Speed

Software: The cameras may be controlled by many popular third party software products, as the are GigE-Vision / Genicam 3.0 compliant. Or you may download the comprehensive and free AT Solution Package, optimized for use with AT’s IR cameras. The SDK is C-based API with wrappers for C++, C# and Python.

Besides the SDK itself, users may want to take advantage of the Metrology Package. The Metrology Package provides a toolset for evaluating measurement results.

Pricing: You might think that a product asserted to be the fastest on the market would come at a premium price. In fact AT’s 3D profilers are priced so competitively that they are often price leaders as well. At the time of writing, they certainly lead on (price : performance) in their class.

EFFI Flex2 Lights – What’s New? 

EFFI-Flex2 LED bar lights

EFFI Flex2 LED bar lights are the next generation modular lights with even more flexibility.

Getting the lighting right is as important as choosing the right sensor, camera, and interface, in terms of machine vision success. Most all lights are “pre-configured” to a specific lighting geometry as well as wavelengths.  Lighting is still tricky and in most cases, testing is needed with various configurations. If your samples are small in size and don’t require special handling or equipment, your imaging partner may offer a lighting lab in which they can test your samples to optimize lighting configuration.

But shipping samples and re-creating your conditions in a partner’s lab isn’t always practical, and you may want to do your own testing and configuration, taking advantage of your domain expertise and home-field advantage. With EFFI Flex2 lights, the standard components and range of settings yield 36 configurations in 1 light! How so? Each unit comes with 3 diffuser windows x 4 lens positions x 3 electronic modes = 36 configurations. Optional additional accessories, like polarizers, take the calculation to more than 100 configurations!

EFFI Flex2 LED modular bar lights are configurable to a wide range of applications.  The user can adapt the optics, the electronics, and the mechanics, thanks to the engineering design.  Perhaps you’ll embed the unit in a “forever” deployment mode, never again re-configuring a specific unit once you lock down the optimal settings.

Or maybe you’ll adapt your light again to repurpose it in another application. With the long service life of LED lights, the light may well outlive the application. Or maybe you do multiple applications, and want a light that’s so versatile you can do all your testing in house, letting the lighting drive the final choice of sensor and camera model.

As with the first generation EFFI-Flex product, EFFI-Flex2 series is designed to provide easy adaptation of:

  • Optics – adjust the lens position and the diffusers
  • Electronics – built-in multimode driver offers 3 operating modes in one light
  • Mechanics – optical lengths from 60mm – 2900mm (factory configured)
One-minute video shows key optical and electronic configuration options

Optically,  lens positions may be user-adjusted for emission angles ranging from from 90 to 10 degrees. Each unit ships with swappable diffusers for strobed light, diffused, semi-diffused, or opaline light. Further, if necessary for your particular application, optional optical accessories are available: polarizer, linescan film, and cylindrical lens).

Electronically, the built-in multimode driver features 3 electronic modes: AutoStrobe with 450% Overdrive, Adjustable Strobe with controlled intensity from 10% to 100%, and Dimmable Continuous with controlled intensity from 10% to 100%. The 450% Overdrive mode is 1.5 times more powerful than the original EFFI-Flex LED bar light in overdrive.

The driver software makes it easy to select among the 3 modes, and the parameters within each mode.

Mechanics: While the length of a given unit cannot be adapted once delivered, one may order in lengths from as short at 60mm to as long as 2900mm. If your default units are English rather than metric, that’s from less than 3 inches to as much as 9.5 feet!

EFFI-Flex original series remains in production. If you don’t require the flexibility of EFFI-Flex2, with up to 36 configurations per unit shipped, the original series offers great value in its own right. Call us at 978-474-0044 to speak with one of our sales engineers, for guidance, or take out your own appendix with this side-by-side comparison diagram:

10GigE cameras join Teledyne DALSA Genie Nano Series

Teledyne DALSA 10GigE Genie Nano

Derived from 10 Gigabit Ethernet, and adapted to GigE Vision standards, Teledyne DALSA has continued buildout of the Nano series from 1GigE, 2GigE, 5GigE, and now 10GigE.

The Genie Nano series is now extended from 1, 2.5 and 5GigE with new 10GigE camera models M/C8200 and M/C6200. These are based on Teledyne e2v’s 67Mp and 37Mp monochrome and color sensors. These high resolution sensors generate a lot of image data to transfer to the host computer, but at 10GigE speeds they achieve frame rates to:

  • 15fps – for the 67Mp cameras
  • 20fps – for the 37Mp cameras

There are four new models offered, in color and monochrome versions for each sensor variant. All are GenICam, GigE Vision 2.0 compliant. They are multi ROI with up to 16 x Region of Interest (ROI). The cameras have all-metal bodies and 3 year warranties.

Further, the M/C8200, at 59 mm x 59 mm, is the industry’s smallest 67M 10GigE Vision camera, for those needing high-resolution and high-performance in a comparatively small form factor.

These 10GigE models share all the other features of the Teledyne DALSA Genie Nano Series, for ease of integration or upgrades. Such features include but are not limited to:

Power over Ethernet (PoE) – single cable solution for power, data, and control

Precision Time Protocol (PTP) synchronization of two or more cameras over GigE network, avoiding the need for hardware triggers and controllers

General Purpose Input Output (GPIO) connectors providing control flexibililty

Trigger to Image Reliability (T2IR)

  • Manage exceptions in a controlled manner
  • Verify critical imaging events such as lost frames, lines, or triggers
  • Tag images for traceability

New Falcon4-M2240 – 2.8Mpix at up to 1200fps!

Teledyne DALSA Falcon4

Who needs another 2.8Mpix camera? In this case it’s not about the pixel count per se, but about the frame rates and the dynamic range.

Falcon™4-CLHS – courtesy Teledyne DALSA

With more common interfaces like GigE and 5GigE we expect frame rates from a 2.8 Mpix camera in the range 20 – 120fps, respectively. But with the Camera Link High Speed (CLHS) interface, Teledyne DALSA’s new Falcon4-M2240 camera can deliver up to 1200fps. If your application demands high-speed performance together with 2.8Mpix resolution, this camera delivers.

Besides speed, an even more remarkable feature of the Falcon4-M2240, based on the Teledyne e2v Lince 2.8 MP, is a pixel well depth, or full well capacity, of ~138 [ke-]. THAT VALUE IS NOT A TYPO!! It really is ~138 [ke-]. Other sensors also thought of as high quality offer pixel well depths only 1/10th of this value, so this sensor is a game changer.

Contact us for a quote

Why does pixel well depth matter? Recall the analogy of photons to raindrops, and pixel wells to buckets. With no raindrops, the bucket is empty, just as with no photons quantized to electrons, the pixel well is empty and the monochrome pixel would correspond to 0 or full-black. When the bucket, or pixel well, becomes exactly full with the last raindrop (electron) it can hold, it’s reached it’s full well capacity – the pixel value would be fully saturated at white (for a monochrome sensor).

The expressive capacity of each pixel admits the widest range of values in correlation to the full well capacity before charge overflows, so the camera is calibrated by the designer according to the sensor’s capabilities. Sensors with higher full well capacity are desirable, since they can capture all the nuances of the imaging target, which in turn gives your software maximum image features to identify.

Falcon4 cameras offer highest performance – courtesy Teledyne DALSA

This newest member of the Falcon4 family joins siblings with sensors offering 11, 37, and 67 Mpix respectively. The Falcon4 family represents continues the success of the Falcon2 family, all of which share many common features: These include:

  • CMOS global shutter
  • High dynamic range
  • 1000x anti-blooming
  • M42 to M95 optics mount
  • Camera Link or Camera Link HS interface
Falcon family members share many features

Even before the new firmware update (V1.02), Falcon4 cameras already offered:

  • Multiple triggering options
  • Multiple exposure control options
  • In sensor binning
  • Gain control
  • In camera Look-up-table (LUT)
  • Pixel correction
  • … and more

Now with Firmware 1.02 the Falcon4 family gets these additional features:

  • Multi-ROI
  • ROI position change by sequencer cycling
  • Digital gain change by sequencer cycling sequencer cycling of Digital Gain
  • Exposure change by sequencer cycling
  • Sequencer cycling of output pulse
  • Meta Data

Multi-ROI

Higher FPS by sending only ROIs needed – courtesy Teledyne DALSA

Region Of Interest (ROI) capabilities are compelling when an application has defined regions within a larger field that can be read out, skipping the un-necessary regions, thereby achieving much higher framerates than having to transfer the full resolution image from camera to host. It’s like having a number of smaller-sensor cameras, each pointed at their own region, but without the complexity of having to manage multiple cameras. As shown in the image below, the composite image frame rates are equivalent to the single ROI speed gains one might have known on other cameras.

Sequencer cycling of ROI position:

Cycling the ROI position for successive images might not seem to have obvious benefits – but what if the host computer could process image 1, while the camera acquires and begins transmitting image 2, and so forth? Overall throughput for the system rises – efficiency gains!

For certain applications, it can be essential to take 2 or more exposures of the same field of view, each under different lighting conditions. Under natural light, one might take a short, medium, and long exposure duration, to hedge on which is best, let the camera or object move to the next position, and let the software decide which is best. Or under controlled lighting, one might image once with white or colored light, then again with an NIR wavelength, knowing that each exposure condition reveals different features relevant to the application.

Metadata:

Metadata may not sound very exciting, and the visuals aren’t that compelling. But sending data along for the ride with each image may be critical for quality control archiving, application analysis and optimization, scheduled maintenance planning, or other reasons of your own choosing. For example, it may be valuable to know at what shutter or gain setting an image was acquired; or to have a timestamp; or to know the device ID from which camera the image came.

The Falcon2 and Falcon4 cameras are designed for use in industrial inspection, robotics, medical, scientific imaging, as well as wide variety of other demanding automated imaging and machine vision applications requiring ultra-high-resolution images.
