Abstract

The present invention relates to an angle measurement sensor and a calibration method thereof, and a calibration method of an angle measurement sensor. The angle measurement sensor comprises: a laserconfigured to emit out a laser beam; a reflector capable of synchronous rotation with a measured object and configured to receive the laser beam emitted by the laser and reflect the laser beam to a refractor; the refractor configured to generate refraction of the laser beam reflected by the reflector and emit out the laser beam; a photoelectric detector configured to receive the laser beam refracted from the refractor and measure the incident position; and a processing system configured to calculate the rotation angle of the measured object according to the incident position variation of the laser beam received by the photoelectric detector. The sensor performs refraction for the reflected laser beam by the refractor so as to amplify the change of the reflection angles before and after rotation, and calculates the rotation angle of the measured angle through the change of the incident angle of the laser on the photoelectric detector.

Description

technical field [0001] The invention relates to the field of measurement technology, in particular to an angle measurement sensor, a calibration method and a measurement method thereof. Background technique [0002] At present, in the field of high-precision measurement of small angles, optical methods are widely used for measurement, such as optical dividing head method, polygonal prism method, diffraction method, self-collimation method, optical fiber method, acousto-optic modulation method, optical internal reflection method, laser interferometry, ring laser method, etc. However, this type of method has small measurement range, high cost and relatively complicated structure. Contents of the invention [0003] The purpose of the present invention is to improve the deficiencies in the prior art and provide an angle measurement sensor. [0004] The technical solution adopted by the present invention to solve its technical problems is: [0005] An angle measurement senso...
