| Abstract: | For the steady question of a self mixing interference system, a mathematics model of the system is deduced based on an effective three mirror cavity model. The boundary of the single solution and multiple ones are given by solving the phase equation of the model. So, the optic feedback level in this system with a stable operating can be determined. This conclusion offers a guide to design the self mixing interference system. |
| Keywords: | optical measurement semiconductor laser self mixing interference steady solution |
