摘要： A first luminous flux emitted from the front end face of a LD is reflected by a mirror to be made incident on a detection point on the surface of a measuring object, and a second luminous flux emitted from the rear end face of the LD is reflected by another mirror to be made incident on the detection point. Scattered light from the first detection point is received in a photodiode. A signal processing circuit part calculates the frequency shift quantity of the scattered light based on output from the photodiode. As a result, a velocimeter is provided which detects the moving speed of a measuring object highly precisely.

摘要： There is provided an optical velocimeter for achieving miniaturization and lower power consumption thereof and for accurately detecting two-dimensional travel velocity of a measured object. This optical velocimeter includes a light-emitting element, a diffraction grating, two light-receiving sections, and a signal processing circuit. Light emitted from the light-emitting element is branched by the diffraction grating into three light fluxes, and optical axes of the divided light fluxes are intersected one another on the measured object to form one detection point. Scattered light from the detection point frequency-shifted by travel of the measured object is then received by the two light-receiving sections, and a light-reception signals outputted from the light-receiving sections are processed in the signal processing circuit to detect travel velocities of two directions of the measured object.
