High-speed polarization camera from Photron measures stress in transparent materials and fluids

Designed by Photron to see and measure stress in transparent materials and fluids at framing rates of over one million frames per second, the high-speed Crysta 2D polarization camera is based on a 1 MPixel CMOS image sensor with a 20 µm pixel size and a pixelated polarizer array made from photon crystal affixed directly to the sensor.

Designed by Photron to see and measure stress in transparent materials and fluids at framing rates of over one million frames per second, thehigh-speed Crysta 2D polarization camera is based on a 1 MPixel CMOS image sensor with a 20 µm pixel size and a pixelated polarizer array made from photon crystal affixed directly to the sensor. This photonic crystal lattice features pixels, in groups of four square, each having a different polarization axis at 0˚, 45˚, 90˚ and 135˚. By applying phase shifting algorithms with circularly-polarized incident light, birefringence phase difference and azimuthal angle can be measured to enable us to quantify and measure physical stress in transparent and semi-transparent fluids and solids at full resolution operation to 7,000 frames per second (fps), and reduced resolution to 1.3 million fps, according to Photron.
