Abstract

PURPOSE:To achieve a driving circuit without beat interference caused by interference due to shift of carrier wave, by connecting a plurality of optical modulators to the same oscillation circuit. CONSTITUTION:A plurality of optical modulators 12, 22 are connected to one oscillator 11, the same carrier wave is modulated with laser beam of different wavelengths and outputted from amplifiers 13, 23. With this constitution, an ultrasonic wave optical modulation driving circuit which can not cause beat interference based on interference due to shift in carrier wave, can be obtained, allowing the provision with the oscillator generating carrier wave of the same frequency and modulators.
