Abstract
Self-mixing interference (SMI) effects have been widely used in measuring the distance and displacement and velocity. Conventional methods are fringe counting and phase analysis. The former method has a precision of λ/10 in a multi-mode LD pumped solid-state laser (LDPSSL), while the latter has a precision of nearly λ/50 concerning the multiple reflections. Theoretical analysis and simulation calculations are presented.
