Abstract:

To enrich the content of university experiment teaching，a new micro-angle measurement method is proposed．The method uses laser self-mixing interference technology and combines the optical characteristics of right-angle prisms，which get the features of a compact system structure and high resolution．The experiment is conducted with a He-Ne laser as the light source，and the measurement range can reach 21.49 mrad．Benefiting from strong operability and expansibility，the proposed experiment can further cultivate students’practical ability and scientific thinking．

Key words: self-mixing angle measurement optical measurement
