Abstract
PURPOSE: To avoid color shift of reproducing picture with a simple mechanism, by radiating three primary colors from one light source and reproducing the picture through the same light axis.
CONSTITUTION: The light intensity of the light from the white color light source 1 is increased via the slit 2 and the intermediate optical system 3, and is incident to the acoustic optical filter 5 as parallel ray 4. The drive circuit of the filter 5 consists of the frequency generator 10, scanning signal generator 11 controlling the output power and scanning frequency of the generator 10 and broadband amplifier 9 connected to the filter 5, and based on the signal separating the color video signal 12 at the signal separation circuit 13, the acoustic frequency corresponding to the wave length of three primary colors can be produced with time sharing system. Further, the filter 5 is swept in acoustic frequency, the light between the corresponding wave lengths is taken as diffractive light 6 and non-diffractive light 7 and they are separated at the slit 8. The color beam thus obtained is fed to polyhedral mirror 17 constituting the light polarized system and pictured on the screen 21 without color shift of reproduced picture.
