Abstract
A method for analyzing the spectrum of the autodyne signal of a semiconductor laser obtained when the reflector moves with acceleration is proposed. The analysis is based on the application of Fresnel integrals to determine the boundary frequencies of the spectrum. The dependence of the spectrum of the autodyne signal on the parameters of the motion of the reflector and the selected observation time interval is investigated. The methods developed as a result of the conducted research for measuring the acceleration of the reflector by the Fourier spectrum of the autodyne signal are demonstrated.
