This technology introduces a new kind of camera sensor in which each pixel functions as a tiny interferometer, instead of a standard light detector. This allows the sensor to capture not only the brightness of a scene but also additional information about the light’s spatial coherence. By leveraging arrays of integrated interferometers, the system...

Snapshot Wavefront Camera

This invention is a reference-free snapshot wavefront camera that can be used to measure both amplitude and phase of the wavefront. The camera uses a two-dimensional diffraction grating to split the incoming wavefront into multiple copies which then travel through a lens that focuses them onto a sensor in a camera array. The resulting wavefront information...
