Dalsa line scan polarization camera makes invisible visible!

Teledyne Dalsa has released the first line scan polarization camera for machine vision. The Piranha4 polarization camera provides the capability of detecting , stress, surface roughness, birefringence and physical properties undetectable with conventional imaging making the invisible visible!

This unique technique uses four polarization channels with a color line scan camera solving various applications, but not limited to the following:

Glass Inspection: Glass bottles, architectural glass sheets, and automobile windshields, etc. – Enables inspection of internal stress and defects non-visible with conventional imaging

Film inspection: transparent films, packaging films, and patterned films etc. – Detect scratches, digs, and other surface defects that are difficult to detect with conventional imaging

Precision optics: optical lens, prisms, fibers, and micro-optical – Detect residual internal stress and thermal annealing effects

Flat Panel Display and PCB inspection: Thin film transistors, organic LEDs, printed circuit boards etc.- inspect ITO, dust particles, films thickness, and surface defects with enhanced contrast

Carbon fibers: effectively inspect the quality of composite materials that are widely used in aircraft, aerospace, wind energy, and automotive industry

Food and material sorting: Increase sorting accuracy and detecting capability of foreign materials such as plastics, glasses, metals etc. with polarization imaging

Bio-medicine: digital pathology, in vitro cells culture, optical coherence tomography etc.- Provides additional information in birefringence tissues
Remote sensing: helps identifying special objects from natural background
And many more…

Line scan polarization camera Features

CMOS Quadlinear sensor – 2048 pixels
High speed line rate of 70k hz with 14.08 um pixels
Camera Link interface
Three polarization states plus and unfiltered channel (Output format with 0 deg (S component), 90 deg (P component), 135 deg and unfiltered polarization states.)

Full specifications on the Teledyne Dalsa polarization camera ( P4-CP-02K07Q-00-R ) can be found HERE

White Paper – Learn about this unique polarization technique with line scan cameras! This white paper covers the following topics

How polarization techniques work in transmission and reflectance configuration

Beware of EMVA 1288 data!

Many camera manufacturers are now putting up EMVA 1288 data. This is test suite created by the European Machine Vision Association (EMVA) that give you the characteristics and performance of cameras, e.g. S/N ratio, noise, etc. , and there are specifications on how to run the tests.

Please note that there is a significant amount of variance allowed within the tests. Each manufacturer has their own test setup, so comparing sensors or product lines from a specific manufacturer is very appropriate.

Comparing results between different manufacturers, especially looking at small details is NOT appropriate. For instance, if Manufacturer A’s test has a 5% variance on what Manufacturer B’s test is on the same sensor, but the difference between the two manufacturers is 5%, there is no valid conclusion! The result is within the variance. Do NOT get sucked into this comparison war.

The EMVA test produces a 30 page report for each specific camera test, testing is across multiple wavelengths, etc. Results that are given in tabular format with one number for each camera are not really a good picture of the test results to compare across manufacturers.

If you want further details, please contact 1stVision. We have conducted many comparison tests and can provide practical advice and discuss it in context of your application.

Advanced Illumination Eurobright Product line prices now reduced 20-50% – Learn more about these IP67 lights with built in controllers!

Advanced Illumination has reduced pricing on their EuroBright lighting product line. This IP67 lighting line provides the highest levels of strobed or continuous operation using “FlexTech” technology and does not require additional controllers.

FlexTech™ is Advanced Illumination’s exclusive technology collection which they have spent years perfecting. This consists of self-sustaining technologies for your system protection and your peace of mind.

The EuroBright Series consists of 6 styles of illuminator’s providing various lighting geometries from area illumination to back lighting. Each light style can be ordered in various wavelengths and has self contained electronics allowing continuous or strobe operation.

EuroBright Illuminators are feature rich with the following key features:

Low cost, feature-rich design
Robust IP67 enclosures
On-board smart driver – seamlessly provides strobe or continuous operation
Adaptive Overdrive – Optimized power under all strobe conditions
Adaptive Power – Optimal heat damage protection
Daisy-chain options in select models
Red, White and Blue wavelengths available.

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!
