World’s Fastest 2D Polarization Camera
Bild: Photron USA, Inc.

The high-speed polarization camera Crysta of Photron utilizes a high-speed 2D birefringence measurement system with a sampling rate of 1.3MHz as the core device of the system with 16 parallel read out circuits in a matrix in the image sensor, which are connected to each pixel with individual A/D converters. The system provides over one million frames per second. The image sensor incorporates a pixelated polarizer array which is made from photonic crystal bonded directly to the CMOS sensor, making the optical system in this sensor resistant to vibration.
