| titleOfInvention | Distance and speed measuring apparatus |
| abstract | To provide a distance and velocity measurement apparatus that can be adopted preferably in a LiDAR or a sensor for a robot, wherein the apparatus can prevent deterioration of SN ratio even in a case where an object in an external environment vibrates. A LiDAR 20 according to the present embodiment includes a first laser apparatus 1 a , a second laser apparatus 1 b , a polarization-maintaining type optical fiber 2 , a WDM filter 6 , an optical fiber coupler 3 a , an optical amplifier 11 , an input/output unit 4 , an optical scanner 5 , a second optical fiber coupler 3 b , a balanced photodetector 7 , and a square-law detector 9 . Further, a delay line 10 composed of a polarization-maintaining optical fiber is provided on the local port 2 b . The first laser apparatus 1 a includes a device for generating a first laser light having a first wavelength and a first chirp rate in an interior thereof, and the second laser apparatus 1 b includes a device for generating a second laser light having a second wavelength that differs from the first wavelength and a second chirp rate that differs from the first chirp rate. |
