An analysis is made of how the emission amplitude and frequency of a semiconductor laser with external optical feedback change as the external reflector is moved. It is shown that the influence of the external optical feedback on the interference signal from vibrations of the reflector can be lessened not only by lowering the feedback level but also through the choice of the distance to the vibrating object.
