Real-time parametric estimation of velocity using optical feedback interferometry

Real-time parametric estimation of velocity using optical feedback interferometry

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