Abstract
A laser radar device () includes: a light source array () for simultaneously emitting a plurality of laser light beams from a plurality of light emitting ends; an optical modulator () for modulating transmission light separated from the plurality of laser light beams to generate modulated transmission light; a transmission/reception optical system () for receiving, as received light, the modulated transmission light reflected by a target, while scanning external space with the modulated transmission light; an optical combiner () for generating a plurality of interference light components by combining a plurality of local light components separated from the plurality of laser light beams and the received light; an optical receiver array () for generating a plurality of detection signals by detecting the plurality of interference light components; a switching circuit () for selecting a detection signal from the plurality of detection signals in accordance with a scanning speed with respect to the external space; and a signal processor () for calculating an observation quantity showing a state of the target on the basis of the selected detection signal.
