Abstract
PURPOSE: To enable the intensities of respective output beams to be determined only by the magnitudes of respective input signals by controlling the intensities of the input beams to an ultrasonic light deflecting element by the correction signal obtainable by the set of input signals.
CONSTITUTION: An ultrasonic light deflecting element 1, driven by the driving signal having plural frequency components fk, diffracts the input beam 3 incident to the deflecting element 1 from a light source 20A to a plurality of intensity-modulated output beams 4. The high frequency driving signal 2 which drives the deflecting element 1 is applied via adder 9 after the input signals ek are applied to plural input terminals 6 and the frequencies fk of oscillators 7-K are amplitude-modulated with a modulator 8-K. On the other hand, the input signals ek are applied to the (K)th extension circuit 13-K and is added in an adder 14. A reference signal 16 is added to the adder 14 and the output 17 of the adder 14 is applied as a correction signal to the modulation input of the light source 20A.
