Experimental research of dynamic spectral filtration using laser radiation interaction with multifrequency acoustic wave

The paper describes the results of experimental research of dynamic spectral filtration using polychromatic laser radiation interaction with multi-frequency acoustic wave. Optical radiation sources were three semiconductor lasers operating in the bands of red, green and blue portions of the spectrum and absorption filters — elements simulating the spectral properties of the reflective surfaces of the target and the background. Instrument function of managed spectral selection device was formed in such a way as to ensure the suppression of spectral components of the background radiation with minimal attenuation of the optical signal of the target
