Abstract
Embodiments of the disclosure provide an optical sensing system containing a diffractive optical element, and an optical sensing method using the same. For example, the optical sensing system includes a laser emitter configured to emit an optical signal. The optical sensing system further includes a steering device configured to direct the emitted optical signal toward an environment surrounding the optical sensing system. The optical sensing system additionally includes a diffractive optical element configured to diffract the optical signal returning from the environment to form a plurality of beams focusing at a plurality of spots on a focal plane. The optical sensing system additionally includes a photosensor array placed at the focal plane, configured to detect the plurality of beams diffracted by the diffractive optical element at the plurality of spots, wherein the photosensor array comprises a plurality of sensitive elements.
