发明名称 Simultaneous multi-beam optical modulation system
摘要 The simultaneous multi-beam optical modulation process comprises the steps of producing a dummy signal in such a manner that the sum of a plurality of signals and the dummy signal is kept constant, modulating the amplitudes of assigned carriers by the dummy signal and the plurality of the signals so as to produce a modulated output and applying the modulated output to an acoustic optical element. An apparatus for carrying out the process is also disclosed.
