Abstract: PURPOSE: An image display device using a projection optical system is provided to control cross-talk in the field of vision which is finally formed using an optical plate and to prevent reduction of resolution per unit time. CONSTITUTION: An image display device comprises a light source(101), a projection optical system(102), a pin hole(103), a first optical plate(104), a screen(105). The projection optical system outputs light which has image information. The pin hole is corresponded to the projection optics one-to-one and diffracts the lights which are outputted from the projection optical system and focuses the lights. The first optical plate images image points in screen from the lights which are outputted from the pin hole and forms the area of the image points smaller than the area of the screen.

Abstract: A system and a method for recording an objective wave, a reference wave and an interference pattern in a digital holography system are provided to measure an objective light and an interference pattern simultaneously by using the polarizing characteristic of light, thereby removing zero-generation diffraction light effectively. A digital holography system(100) uses an interferometer structure for removing a zero-generation diffraction light effectively. A laser(101) generates light by using a coherent light source. A light diffuser(102) diffuses the light generated by the laser. A light divider(104,108) divides the diffused light into an objective light and a reference light. At least one reflector(106) reflects the objective light or/and the reference light. A first CCD(Charge Coupled Device)(112) records the objective light. A second CCD(110) records an interference pattern between the objective light and the reference light, and the objective light and the interference pattern are simultaneously recorded.
