Abstract
PURPOSE: To make it possible to display the same three-dimensional image as the actual image by means of a simple constitution, by varying a laser light beam two- dimensionally by the photodeflection device, irradiating it on the screen, and displacing back and forth this screen.
CONSTITUTION: A laser light beam 26 from the laser light source 20 is varied as to its intensity of light in accordance with an electric signal of the photomodulator 21, and is made incident to the photodeflection device DX. The reflector 23 swings the beam 26 in the X axial direction on the screen 27 in accordance with the input current. In the same way, the beam 26 is swung in the Y axial direction by the deflection device DY. On the other hand, the screen 27 is made to perform the reciprocating motion back and forth through the motor 32, the crank 31, and the sliders 18, 19. By means of this constitution, when the screen is made to perform the reciprocating motion at 30 cycles per second, and the beam 26 is deflected by DX and DY and is irradiated onthe screen 27 by the prescribed electric signal, a three- dimensional solid image can be perceived by the residual image phenomenon.
