Self-mixing interferometry (SMI) is a technique that is capable of measuring rotational speed in a direct way. Thus, SMI is an attractive alternative to optical encoders with respect to speed detection. But problems such as additive noises as well as amplitude and frequency modulation due to spectral broadening make the usage of self-mixing interferometry challenging. In this paper, a signal processing method with relative high accuracy is presented for rotational speed measurement using SMI. The method uses of signal selectio
