| titleOfInvention | Doppler device of speed measuring instrument based on fabry-perot interferometer with fibre input of radiation |
| abstract | FIELD: measuring equipment. n SUBSTANCE: invention belongs to measuring instruments of speed by the interferometric method by Doppler shift of length of a wave of light reflected from a studied object, with use of the Fabry-Perot interferometer and can be used for increase in brightness of an interferential picture on a slot-hole diaphragm at the outlet of the optical system 2-10 times with small increase in dimensions. The technical result is reached by the fact that the device of a Doppler measuring instrument of speed on the basis of a Fabry-Perot interferometer with fibre input of radiation, containing the following components serially located on one optical axis a cylindrical lens with positive focal length, a Fabry-Perot interferometer, a long-focus building lens, in the focal plane of which there is a slot-hole diaphragm and a detector, contains components serially located on one optical axis before a cylindrical lens with positive focal length a collimating lens and two cylindrical lenses with negative focal length. n EFFECT: reduction of dimensions of optical system, possibility to use light transfer along optical fibre and increase in illumination of a slot-hole diaphragm of a registrar. n 4 dwg |
