Tech sees differently, and can fuse multiple types of data we can’t even perceive: lidar, IR, ultrasonic, and so on. Metalenz, maker of highly compact “2D” cameras for advanced sensing, hopes to bring polarized light into the mix for security and safety with its PolarEyes tech.
Polarization isn’t a quality of light that’s often paid much attention. It has to do with the orientation of the photon’s movement as it waves its way through the air, and generally you can get the info you need from light without checking its polarization. But that doesn’t mean it’s useless.
“Polarization generally gets thrown out, but it really can tell you something about what the objects you’re l …
