Teledyne Dalsa TurboDrive 2.0 breaks past GigE limits now with 6 levels of compression

Teledyne Dalsa introduces TurboDrive 2.0 for their Genie Nanos

With the introduction of the Genie Nano came Turbodrive which allowed ‘faster GigE than GigE’ speeds. Turbodrive is a lossless hardware encoding scheme that potentially reduces the amount of data to be transmitted from the camera to the computer. Dalsa’s Nanos, which are priced identical to the competition, offers the users the ability to go faster at no extra cost. Note that the user can turn on or off the encoding.

However, the encoding scheme is data content dependent, and therefore if your data varies a lot within an image the compression is minimal. If your data varies a lot from image to image, then using the encoding means that only certain frames will get a speedup resulting in an inconsistent data transfer rate.

Teledyne Dalsa has just recently introduced TurboDrive 2.0, a firmware upgrade for all Nanos. The major enhancement is that now TurboDrive offers multiple levels of encoding. Level 0 is lossless, and each successive level has some potential lossy amount.

The table below indicates quality level, image compression ratio (absolute worst case scenario) and effective bandwidth gain

As you can see, at level 6, you have a worst case compression of 0.33, yet a speed up of 3. Note, this is a worst case situation so you might get a speed up of 3x, yet be at 0.8. The algorithm is data dependent! (more about this in the tech primer)

Depending on the application, various compression levels provide minimal degradation. The following images are shown for comparisons using the varying quality levels.

As you can see, even at level 4, there is very little degradation in the image. It is easy to imagine that with this image, you can still do your image processing yet get a speed up of 68%!

Level 0 “Lossless” to Level 6 indicate the quality level in the images.

What are the benefits of FlexTech technology?

In essence, FlexTech technology maximizes intensity even in varied temperature conditions ensuring the illuminator is providing maximum performance and protected.

You do not have to worry about over driving the light source.. FlexTech does this for you!

What benefits does FlexTechnology bring to EuroBright Illuminators?

Adaptive Overdrive

Adaptive Overdrive™ shapes the output pulse of the illuminator to maximize the intensity seen in the image. This technology allows for a very flexible on-board driver where the output is always performing at its peak with any camera exposures.

Adaptive Power

Adaptive Power allows for the user to “train” the light to operate in varied external temperatures. This was designed primarily for the EuroBrite™ Series of lights. Training allows the controller to identify the correct operational current such that the light does not overheat. Adaptive Power guarantees maximum brightness and lifetime regardless of the installation.

Smart Power Allocation

Smart Power Allocation performs load-balancing to be sure each individual channel on a controller is always being utilized to its fullest. Rather than relying on a fixed “current” for a light, factors such as voltage and string combination are considered in determining the correct operating range. Standard products have up to a 30% higher output with this feature enabled.

Packed with features, EuroBright illuminators are one of the most advanced lights on the market for a great price!

Allied Vision’s high-resolution Prosilica GT now with 12, 16 and 25MP ON Semi PYTHON sensors

Allied Vision extends its Prosilica GT Large Format camera platform with three high-resolution ON Semi PYTHON image sensors (Python 12K, Python 16K & Python 25K)

Combined with robust thermal housing designed to operate in extended temperature ranges and fluctuating lighting conditions, the new Prosilica GT Large Format cameras are ideal for high-definition imaging applications with demanding requirements of robustness and design-in flexibility. They provide a great option for high-quality imaging for anyone looking to switch over from existing CCD cameras to CMOS cameras with similar resolutions and optical formats.

Features include:

Extended temperature range (-20 deg. C to + 50 deg. C)
NIR sensitivity up to 1100nm
Modular concept providing various lens mounts (M58, M42, and EF-mount)
Fixed Pattern noise correction, Defect Pixel Correction, and Trigger over Ethernet.

Prosilica GT5120, Prosilica GT4096, and Prosilica GT4090 at a glance

See full specification for the series below:

Prosilica GT5120, 5120 x 5120, 25MP

Prosilica GT4096, 4096 x 4096, 16MP
This is a great replacement for the KAI-16000 CCD sensors!

Prosilica GT4090, 4096 x 3092, 12MP

Now that you have a great high resolution camera, what lens works best?

High resolution cameras with the ON Semi Python sensors are great, but only as good as the lenses you use! It is imperative to have the sensor sizes matched with the lens formats. Additionally, we need to make sure the lens resolution is adequate for the image sensor pixel size.

To aid in the lens selection, we have the following recommendation on lens series. Recommendations as follows

Prosilica GT5120, 5120 x 5120, 25MP: This camera has a 32.58mm diagonal image sensor, so a F-mount lens is required. Two options are Kowa and Schneider
KOWA – F mount series
Schneider – F mount series

Prosilica GT4096, 4096 x 4096, 16MP: This camera has a 26.06mm diagonal image sensor, also requiring a F-mount lens.
KOWA – F mount series
Schneider – F mount series

Prosilica GT4090, 4096 x 3092, 12MP : This camera has a 23.09mm diagonal image sensor which falls into a 4/3″ format.
KOWA 4/3″ lens series

As a note, as the pixel size is 4.5um, this is not as demanding on the lens resolution and will only require 111 line pairs/mm (lp/mm) making these adequate selections.

Sony has a great new 1.1” Image Sensor, but what kind of lens can I use with this format? Computar MPY Series!

Computar MPY Series Lenses — Computar MPY lens series

If you have been around industrial camera lenses for a while, you know that there are many ½” and 2/3” lenses, not as many 1” lenses, but what do you do when you have a 1.1” sensor?! The solution? Use the Computar MPY 12 Megapixel lenses!

If you have been following Sony’s new IMX image sensor product line, their newest sensors are based on a 3.65um pixel pitch. However, when you scale this up to their new 12MP sensor (Sony Pregius IMX253, IMX304), the sensor size becomes 1.1” (17.6mm diagonal) format. A 1” lens format will not cover this image circle and in turn has vignetting in your image (Read our blog post on sensor size vs. lens size ) .

One possible solution is to use a 1” lens and vignette 5% on each side, or use a 1” lens and stop it down where the vignetting goes away. However this is not an optimal solution. A second solution is to use a F Mount lens, but if the camera is a C mount, you will need a C to F adapter, again less than ideal.

Fortunately there are some C mount lenses that are greater than a 1” image format. Kowa and Schneider both have been shipping 4/3” format lenses, although these are quite expensive. Recently, Computar has come out with a line of 1.1” format lenses SPECIFICALLY for this sensor!

Key Features of the 1.1″ format, Computar MPY 12MP C-mount lenses
