ABSTRACT
A novel rotational velocity measurement method based on the self-mixing grating interferometer (SMGI) is explored and presented in this paper. In this method, the target object rotational velocity is measured by the Doppler frequency shift, which can be extracted through the power spectrum without measuring incident angles. The experimental results show that the relative errors are below 0.5%.
