Optimal processing of the laser doppler vibrometer signals

Two methods for optimal processing of laser Doppler vibrometer (LDV) signal are considered. The structure of the device of optimal nonlinear filtering of the parameter, associated with the oscillations amplitude, is found. The characteristics of a simplified filtering algorithm are discussed. Under certain assumptions, the task of optimal estimation of the relative amplitude of oscillations is solved. The characteristics of the estimates are considered.
