A unit cell, a system, and a method for detection of light from a target. Interuniversity Microelectronics Centre
A unit cell (100; 200; 300) for detection of light from a target comprises: a light emitting unit (110; 210; 310) for emitting coherent light towards the target; an extractor (120; 220; 320) for extracting part of the emitted coherent light to form reference light; at least one photo-sensitive element (130, 132; 230a-h; 330, 332), each configured to receive light from the target based on emitted coherent light and to receive reference light for detecting both light from the target and reference light; wherein the unit cell (100; 200; 300) defines an optical path for reference light between ...
