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

Dalsa Polorized ruler

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   Dalsa Polarized scratch

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

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…

Dalsa Linea – GigE 80kHz LineScan @ $1100

Dalsa’s newest innovation is cost!

Introducing Linea, a CMOS line scan camera that can help you improve your imaging and lower your costs. Linea starts with an advanced CMOS sensor with high quantum efficiency and low noise for better images. Linea is also packed with advanced features to make your machine vision job almost effortless.

Linea uses Teledyne DALSA’s own advanced CMOS line scan sensors which are available in resolutions from 2k to 16k.

Extensive Feature Set

TurboDrive™ technology allows Linea GigE to deliver its full image quality at line rates up to 80 kHz—several times faster than competitors—with no changes to your GigE network.

    Multiple Regions of Interest to let you reduce your data transfer and processing load — all of which not only help boost performance but also reduce your system cost.

      Burst Modes can take advantage of its high speed sensor by capturing and buffering high speed bursts faster than GigE allows.

      HDR (High Dynamic Range) lets you combine short and long exposures to see details in bright and dark areas at the same time.

      Cycling Mode lets you change your settings every line and cycle through up to five different user-controlled configurations.  This allows use of different light sources, lighting angles, exposure time and gain from a single pass.

      Trigger to Image Reliability framework gives you data reliability peace and of mind by controlling and monitoring the entire image capture process from trigger through image capture and transfer to host memory, protecting you from data loss and improving the reliability of your inspection system.

        Suited for applications in postal, pharmaceutical, print, material and food inspection, Linea is a smart choice with low cost and excellent performance. 

        Full data sheets for linear are available HERE
