<P>PROBLEM TO BE SOLVED: To provide a projection device for projecting a visible full color image without occurence of deviation for each pixel with a simple constitution, and a color perception inspection device. <P>SOLUTION: A projection device 100 includes: a light source unit 10 including an elliptical mirror 11, a light source 12, a light pipe 13, and a slit 14, and for emitting white light; a diffraction grating 20 for generating diffraction light of the white light as light beams subjected to color separation; a galvano mirror 30 for polarizing and scanning the light beams to subject the light beams of respective colors to time division; an image forming optical system 40 for forming an image of the light beams polarized and scanned; an image forming element 50 disposed at an image forming position of the image forming optical system and for modulating the incident light beams of the respective colors for each pixel based on an image signal to generate an image; and a projection optical system. In addition, a color perception inspection device includes the projection device 100 and a diffusion plate to receive illumination light. <P>COPYRIGHT: (C)2012,JPO&INPIT |
