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...
