Abstract
This work describes a novel elaboration of a self-mixing optical interferometer, able to reconstruct the target speed and direction, without using heterodyne detection. The elaboration employs the signal non-linearity in order to recover the speed sign in the frequency domain. The target speed is measured by the signal frequency, while the speed sign is evaluated by the phase of the harmonics in the frequency domain.
