A low-cost optical feedback interferometer for real-time velocity measurement

A low-cost laser sensor using optical feedback interferometry has been designed to measure velocities. With a digital signal processing based on an order 2 autoregressive model of the optical power, an accuracy of about 0.5% can be reached.
