Abstract
In the present paper, the effects of periodic nonsinusoidal vibrations of spatial filters in signal detection experiments are considered. Performance degradation of such an optical information processing system is shown graphically, assuming that the signal is buried in noise of uniform spectral density. Results are compared with those in the presence of pure sinusoidal vibrations of the spatial filter. It is observed that the performance of the system decreases with the increase in departure from the pure sinusoidal case.
