Fig. 5. (a) Coefficient of the optical path variation with temperature when the incident angle θs is constant and the thickness Ls is variable. (b) Coefficient of the optical path variation with temperature when the thickness Ls is constant and the incident angle θs is variable.
Fig. 6. Optical path of the heterodyne laser interferometer, which refers to LPF, is designed with a compensator. Laser 1 and Laser 2 are the heterodyne laser sources obtained by acousto-optical modulators (AOMs).
Fig. 7. Relationship of the temperature and optical coupling coefficient and the incident angle of the compensator. The black line is the result of the theoretical model, and the red dots are the results of the COMSOL simulation.
