Marketwired: Teledyne Dalsa announces production of the new Polarization camera in its Piranha family. First announced in Q2 2017, the Piranha4 Polarization camera is now in full production with improved performance.

The camera uses a quadlinear CMOS sensor with nanowire micro-polarizer filters. It captures multiple native polarization state data without any interpolation. With a maximum line rate of 70 kHz, the camera outputs independent images of 0°(s), 90° (p), and 135° polarization states as well as an unfiltered channel.

Polarization brings vision technology to the next level for many industrial applications. It detects material properties such as birefringence, stress, film, composition, and grading etc. that are not detectable using conventional imaging,” said Xing-Fei He, Senior Product Manager.
