摘要：

Certain flexibility in an optical filter experiment can be achieved with coherent optical feedback because the transfer function of such systems depends on an adjustable phase. With a simple filter in the optical system, a spatial bandpass characteristic is attainable. The tuning frequency of the bandpass is a function of the phase of the feedback signal. The variable bandpass effect is demonstrated with different inputs. © 1979 Optical Society of America.
