摘要： An optical system having an iris controlled in real time and a control method of amount of light thereof. The optical system includes a light source, a light modulator modulating a light emitted from the light source to a certain image, a driving part controlling the light modulator to produce the certain image and outputting luminance information of the certain image, a projector projecting the certain image, a screen on which the projected image is formed, a projection iris controlling an amount of light projected from the light modulator onto the screen, and a iris controller receiving the luminance information of the certain image from the driving part and controlling the projection iris corresponding to the luminance information of the certain image. Since the opening range of the iris is controlled in real time, the contrast ratio (C/R) is improved.

摘要： A light tunnel and a projection apparatus having the same provide an improved degree of optical separation and an improved image forming efficiency. The light tunnel standardizes the intensity distribution of light emitted from a light source. The light tunnel comprises an incident plane and an emitting plane for the light. In addition, the size of the emitting plane is larger than that of the incident plane, and the emitting plane is inclined at a certain angle (θ) relative to the incident plane. With this configuration, the degree of optical separation and image forming efficiency of an illumination light is improved. The improved degree of optical separation also improves the contrast ratio, while allowing a compact optical system.
