Additionally, the device is said to offer polarisation for both area and line scan (Piranha(TM)4 polarization) cameras. Polarisation enables detectability of stress, birefringence, through-reflection and glare from surfaces like glass, plastic and metal.
Sony's image sensor, with its pixel-level polariser structure, intends to enable the detection of the amount and angle of polarised light across a scene. Four angled polarisers (90°, 45°, 135° and 0°) are positioned on each pixel, with every block of four pixels comprising a calculation unit.
