A novel elaboration technique for a self-mixing interferometer is presented. It enables the measurement of speed and direction for a remote target, without using heterodyne detection. The elaboration employs the signal non-linearity for recovering the speed sign directly in the frequency domain. The target speed is measured by the signal frequency, whereas the speed sign is evaluated by the phases of the signal.

Abstract
A novel elaboration technique for a self-mixing interferometer is presented. It enables the measurement of speed and direction for a remote target, without using heterodyne detection. The elaboration employs the signal non-linearity for recovering the speed sign directly in the frequency domain. The target speed is measured by the signal frequency, whereas the speed sign is evaluated by the phases of the signal.File in questo prodotto:
