Optical Sensors are devices that detect and convert light, across visible, infrared, or other wavelengths, into electrical signals for measurement or imaging. They include cameras, photodiodes, depth sensors, and structured-light or time-of-flight units used to capture scene geometry and motion. In capture and recognition systems they provide the primary visual input from which 3D structure, pose, and identity are inferred.

- The category spans cameras, photodiodes, depth sensors, and time-of-flight and structured-light units. Their resolution, frame rate, and depth fidelity determine how accurately downstream pipelines reconstruct 3D geometry, motion, and identity from a scene.
