Abstract
A laser radar device includes: a modulator () for causing a transmission seed light beam to branch, and giving different offset frequencies to a plurality of the transmission seed light beams having branched, and then modulating the plurality of transmission seed light beams into pulsed light beams and outputting the pulsed light beams, or for modulating the transmission seed light beam into a pulsed light beam, causing the pulsed light beam to branch, and giving the different offset frequencies to a plurality of the pulsed light beams having branched, and then outputting the plurality of pulsed light beams; a band pass filter () in which a frequency band including frequencies of signal components included in a plurality of beat signals detected by an optical heterodyne receiver () is set as a pass band and a frequency band not including the frequencies of the signal components is set as a cutoff band; and an ADC () for sampling the beat signals passing through the band pass filter () at a sampling frequency.
