    摘要： A Doppler velocity meter has a radiation source for emitting a radiation beam the wavelength of which fluctuates, such as a laser; an optical system for directing the radiation beam to an object at an incident angle .theta. and a detector for detecting scattered beam generated from the object by directing the radiation beam. The optical system has a diffraction grating which serves to change the incident angle .theta. in accordance with a change in the wavelength .lambda. of the radiation beam in such a manner as to maintain the value of sin .theta./.lambda. substantially constant. The velocity meter can accurately detect the velocity of movement of the object regardless of any change in the wavelength .lambda., because the diffraction grating serves to substantially compensate for any change in the frequency of the scattered beam caused by the change in the wavelength.

    摘要： An apparatus for detecting the velocity information of an object comprises the irradiation optical system for performing the irradiation of beam to the predetermined position on an object to be measured; the photodetector for detecting the light from the irradiated object by the irradiation optical system, the velocity information being obtained by the detection; the detector for detecting the irradiating state for detecting the deviation of the irradiating position of the beam on the object to be measured; and the adjuster for adjusting the irradiating state of the beam on the object based on the detection result of the detector for detecting the irradiating state. With such constituents as above, the apparatus is capable of dealing with the fluctuation of the lightning to obtain a high-precision detection of the velocity information at a high speed.
