Abstract: The laser radar includes a clock generator, a projection unit configured to project pulse laser light in synchronization with a clock signal, a light reception unit configured to receive reflected light, a counter configured to count a counter value which is the number of clock signals generated from a projection timing until a light reception timing, a delay circuit in which a plurality of stages of delay units are connected and to which the clock signal is successively input, and a time calculation unit configured to calculate a round trip time of the pulse laser light on the basis of the counter value and the number of hops which is the number of stages of the delay units to which a head of the clock signal is transmitted in a period of the clock signal including the light reception timing.
