ABSTRACT:
A velocity information detecting apparatus detects velocity information of a moving object. The apparatus is provided with a light source for emitting a coherent beam, a beam splitting member for splitting the beam from the light source into a plurality of beams to irradiate the object thereby, and a photodetector for receiving scattered light from the object. The velocity information of the object is detected, based on a Doppler shift of the scattered light detected by the photodetector. The plurality of beams irradiate the object disposed in a region before the plurality of beams are spatially separated from each other. The beam splitting member may be either a diffraction grating or a prism member. The diffraction grating may be a lamellar phase grating or a blazed diffraction grating. The prism member may be a roof prism.
