A laser rangefinder includes a laser emitter for emitting parallel laser beams, a micro electro mechanical system reflector including a plurality of micro reflecting units and 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, a time interval counter configured for recording the 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, and a processor configured for calculating the distances to the different points of the object based on the time intervals.
