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

Measurement of Space Optics and Structures

This paper presents an overview of the techniques and configurations used to build dynamic interferometers and measurement results for a variety of space-based optical components.

Vibrational Characteristics of Light-weight Mirrors

We present a technique to characterize and quantitatively measure the vibrational mode shapes and amplitudes of mirrors concurrently with surface figure testing..
