    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.
