Abstract

The invention relates to a self-mixing reflective sensor, preferably VCSEL-based, which does not require a separate photodetector nor complicated signal- processing circuitry. The measurement principle is based on a detection of the self- mixing oscillation amplitude rather than the oscillation frequency of the self-mixing signal.
