4D Technology Corporation, manufacturer of optical measurement systems, has introduced two new models to its line of PolarCam Polarization Cameras.

The PolarCam snapshot micropolarizer camera simultaneously captures images at  4 polarization angles from each video frame, enabling a range of image enhancement techniques and polarimetric measurements. Compact, fast and field-proven, these unique cameras serve applications in process control, medical imaging, remote sensing and more.

Two new PolarCam models utilize CMOS technology sensors, enabling up to 170 frames/second imaging rate at  1248 x 1082 pixel resolution. This increased speed is particularly suitable for  high speed, in line process control and high resolution capture of moving parts and changing scenes. Customizable regions of interest make it possible to process a subset of the acquired pixels, resulting in frame rates in the kilohertz range.

Optional PolarView software provides real-time display and calculation of key polarization parameters, including Degree and Angle of Linear Polarization, S0, S1 and S2 Stokes parameters, and an Enhanced Polarization Image. Use the many included tools to process and analyze the data, then save images and movies of any parameter to disk for comprehensive analysis.

PolarCam cameras are available with 0.29, 1.4, 1.6 and 3.8 mega-pixel sensors. Video rate of up to 259 full frames per second ensures fast capture of rapidly changing scenes.

Applications include: image enhancement, birefringence measurement, industrial monitoring, stress and strain characterization, 3D reconstruction, medical imaging and autonomous vehicle vision.
