Abstract: There are provided an optical receiver and a laser radar including the same. The optical receiver includes a plurality of optical detecting units configured to convert an optical signal reflected from a target into an electrical signal and to output the electrical signal, a signal combiner configured to combine output signals of the plurality of light detecting regions, a plurality of switches provided between the plurality of optical detecting units and the signal combiner, and a controller configured to control the plurality of switches so that the plurality of optical detecting units are selectively connected to the signal combiner based on whether the optical signal to reflected from the target is input. Therefore, it is possible to make a module small, to improve stability and reliability, and to reduce a signal to noise ratio.

Abstract: Disclosed is a laser radar apparatus. The laser radar apparatus includes: a light transmission unit configured to output a laser pulse by using a light source; a light reception unit configured to receive a reflected laser pulse in connection with the laser pulse; and a controller configured to adjust a repetition rate of the laser pulse of the light source, in which the controller adjusts the repetition rate of the laser pulse based on at least one of reception power, a target distance, a movement speed, a vertical angle, and a radiation angle.
