- Abstract:
-
The disappearanee of self-mixing interlerenee fringes in the high feedbaek-regime decreases thelisplacement measurement aeeuraey. The proposed method based on Lang-Kobayashi equation deteets thefringe-loss with a large oplical feedback faetor C. And the relationship between C and m which represents thenumber of fringe-loss in half cyele is oblained: C<4.6,m=0:4.6≤C<4.8,m=1:4.8≤C<7.9.m=2. Aself-mixing interferenee displaeement measurement algorithm is presented that is able to remedy the inllueneeof fringe-loss. The measurement accuraey is improved greatly.
