Description

Technical Field

[0001] The utility model relates to the technical field of interferometer calibration, and more specifically, to an angle measurement and calibration device for an interferometer. Background Art

[0002] When the laser interferometer measures angles, the laser emitted by the laser head is divided into two paths in the angle interferometer, which point to the two corner cube prisms in the angle reflector respectively; when the angle reflector rotates as a whole by an angle α, the optical path difference between the two beams of light reflected back by the corner cube prism changes by δ. When the interferometer is measured, the light source emitted by the laser head will produce an angle tilt. In order to ensure the accuracy of the measurement, the angle interferometer needs to be adjusted, thereby adjusting the light source path of the laser.
