PROBLEM TO BE SOLVED: To provide a laser radar device with detection accuracy enhanced on a measured distance to a detected body without causing the upsizing of the device. SOLUTION: When a light introduction part 75 exists on an optical axis of laser light L0, part of the laser light L0 is guided by an optical fiber 74 to outgo to a photodiode 20. Further, a distance correcting value Xc is calculated according to a light guiding time T and a distance Xf in a light guiding direction, the guiding time T being between when laser light L0 is generated in a laser diode 10 and when part of the laser light L0 is guided by the optical fiber 74 and detected by the photodiode 20. A measured distance X is corrected based on the correcting value Xc. COPYRIGHT: (C)2010,JPO&INPIT
