Can a laser interferometer measure angles? How to measure?

Laser interferometer can measure the angle, mainly used in the movement of the axis of the angular pendulum measurement and rotary axis of the rotation angle measurement.

SJ6000 laser interferometer angle measurement principle is as follows:

Angle reflector rotates to generate the corner, or move the process of angular pendulum, the two beams of reflected light there will be a corresponding difference in the optical range generated by the SJ6000 collected the difference in the optical range of the interference signal, after the arithmetic processing, you can derive the corresponding angle value.

Laser interferometer measurement angle basic configuration:

Angle measurement configuration mainly consists of SJ6000 host, angle mirror group, SJ6000 static measurement software and other components, can meet the ± 10 ° range of angle measurement.
