ABSTRACT:
The simultaneous multi-beam optical modulation process comprises the steps of obtaining a plurality of modulated signals with the amplitude of carriers having different frequencies modulated by a plurality of signals, and driving an acoustic optical element by the modulated signals so that a light modulation is performed by the acoustic optical element. In this system, a dummy signal is produced by squaring a plurality of the signals and adding and then inverting the squared signals and a setting voltage for setting an overall deflection efficiency of the acoustic optical element, or by adding and then inverting a plurality of the signals and the setting voltage and then squaring the sum. The amplitude of an assigned carrier is modulated by the dummy signal and a modulated output is obtained. The modulated output and the modulated signals are summed up into a summed-up signal, which is then applied to the acoustic optical system. An apparatus for carrying out the process is also described.
