Abstract

PURPOSE: To simplify the constitution of the laser color recorder by entering two light beams of different wavelengths to one acousto-optic element, modulating two carriers with two color signals respectively and applying the same to the acousto- optic element.
CONSTITUTION: Light beams of different wavelengths emitted from lasers 16, 17 are combined to one beam by dichroic mirrors 18, 19 and this beam is entered to an acousto-optic element 20. The carriers from high frequency oscillators 21, 22 are modulated respectively by modulators 23, 24 by the black-and-white signal A and red signal B from a picture signal source and are combined to one with a synthesizer 25. This is then amplified with an amplifier 26 and is applied to the acousto-optic element 20. Here if the carrier frequencies are so selected that the directions θ of the two polarizing beams coincide, then the lasers from the lasers 16, 17 are modulated respectively to the black-and-white signals and red signal by the acousto- optic element 20 and are fetched out through a slit 27. If this way, the constitution of the layer two color recorder may be simplified.
