Paper Abstract

The experimental investigation of the problem of collinear acousto-optic tunable filters driven by successive variable acoustic pulses is carried out. It is shown that in the case of acoustic pulse of a stepped from the substantial suppression of the transmission function side lobes can be observed. The influence of the acoustic pulses number situated in the crystal simultaneously and their duration on the collinear filter apparatus function was investigated. It is found that in this case the apparatus function consists of a number of a narrow peaks and the distance between them depend on the number of pulses in crystal, while the number of peaks depends on the each acoustic pulse duration. The investigation of spectrum consisting of tow close lines was carried out with a help of collinear acousto-optic tunable filter.
