摘要：
The problem of controlling the characteristics of collinear acousto-optical filters is studied experimentally. It is shown that the use of an acoustic pulse in the form of a step-function signal makes it possible to considerably reduce the side lobes of the instrument function of a collinear acousto-optical filter. The changes in the shape of the transmission curve that occur as a result of the variations in the number of acoustic pulses simultaneously propagating in the crystal and in their duration are investigated. An experimental study of a spectrum consisting of two close lines is performed using a tunable collinear acousto-optical filter.
