Abstract

PURPOSE: To obviate the occurrence of cross modulation without interposing any amplifier between power synthesizers and acousto-optic element by amplifying plural signals with respective amplifiers then synthesizing with power synthesizers and applying the signals to an acousto-optic element.
CONSTITUTION: Respective modulators M1, M2... pulse-modulate the carriers of the carrier oscillators fc1, fc2... whose oscillation frequencies oppose to the positions of primary diffracted light I11, I12... with the pulse signals corresponding to the picture signals from signal sources fs1, fs2... and output the same to respective amplifiers A1, A2... The amplifiers A1... simply necessitate the frequency bands corresponding to the modulation frequencies and since the carrier is one, the problem of cross modulation does not occur. The output signals of the respective amplifiers A1, A2... are subsequently synthesized each two in a tournament system by power amplifiers FM11, FM12... and are finally made to one, which is then applied to an acousto-optic element AO.
