Vision systems

Helping machines to see

Polarizing camera PolarCam has been used to image the sun’s corona during the eclipse, demonstrating unique, real-time measurements of polarization in the sun’s atmosphere.


Imaging for autonomous travel

Polarimetry can be used to see obscured man-made objects in natural environments. It’s also capable of generating 3D imagery from a single frame, which could be extra-useful in driver-assist artificial intelligence programs.  

Added Technical Resources

R&D subjects for polarimetry snapshot calendars

This paper presents several fields of study for which polarimeter snapshot cameras are being researched. Topics include biocellular imaging, autonomous vehicle vision, and more.
