Area Cameras Feature Sony’s Polarized Image Sensor

(Teledyne DALSA)

Teledyne DALSA’s latest Genie Nano camera employs a Sony Pregius 5.1M polarized image sensor. The camera features a monochrome quad polarization filter, resolution of 2448 x 2048 pixels, and image capture of 35 fps. Using the company’s TurboDrive technology, frame rates can increase by as much as 50%.


With the debut of the Genie Nano polarized model, Teledyne DALSA is allegedly the first company to offer polarization for both area and line scan cameras. Polarization enables detectability of stress, birefringence, through-reflection and glare from surfaces like glass, plastic, and metal. Sony’s image sensor, with its pixel-level polarizer structure, enables the detection of both the amount and angle of polarized light across a scene. Four different angled polarizers (90°, 45°, 135° and 0°) are positioned on each pixel, and every block of four pixels comprises a calculation unit.
