Abstract:
1. A laser rangefinder, comprising: a laser emitter for emitting parallel laser beams; a micro electro mechanical system reflector including a plurality of micro reflecting units configured for reflecting the parallel laser beams toward different points on an object; a micro electro mechanical system photoreceiver configured for receiving the laser beams reflected by and from the different points on the object, the micro electro mechanical system photoreceiver comprising a substrate, and a plurality of the receiving units arranged in an array and positioned on the substrate, corresponding to the reflecting units; a time interval counter configured for recording time intervals between a first time when the laser emitter emitting the parallel laser beams and second times when the laser beams are received by the micro electro mechanical system photoreceiver; a processor configured for calculating the distances to the different points of the object based on the time intervals.
