摘要： A projection system that includes a singe light modulation device and a plurality of light sources of different wavelengths. Each wavelength of light is incident on the light modulation device at a spatially distinct location and a temporally distinct time. The use of a scanning mirror allows the projection system to sequentially form, in full-color, each of the columns or rows of an image. The projection system is characterized by the reduction of color separation or the rainbow effect due to the rendering of each column or row in full color.

摘要： Disclosed is a color wheel for projectors, comprising a disk-shaped support which is rotatable about the central axis and is provided with planar monolithic color filter segments that are mounted on the support. Said color filter segments are oriented in a radial direction relative to the axis of rotation and form an annular area on the periphery of the support, said annular area being concentric to the center. The circumference of the color filter segments encompasses two radial zones, each of which is provided with at least one indentation such that the indentations of adjacent color filter segments jointly form holes into which pins located on the support are inserted in a positive manner.

摘要： A projection system for projecting images is described. The projection system has an illumination system for generating an illumination beam comprising sequential color portions. The illumination beam is guided to a light modulating means based on light valves, which allows modulating an impinging illumination beam such that it comprises image information about an image to be displayed. The images are refreshed after an image frame time t frame . The illumination of the light modulating means for generating an image is substantially performed during a first time interval of the image frame time t frame . The latter results in an improved displaying of fast moving images.

摘要： A projection-type video display apparatus has a polarizing beam splitter for matching light, which is outputted by a light source unit, to one of S polarizing light and P polarizing light, an optical characteristics switching element for electrically and periodically switching a wavelength band of light outputted by the polarizing beam splitter, a video display element, as a light valve element, for forming an optical image from light outputted by the light source unit, in accordance with a video signal, and a radiating unit for radiating a plurality of color light, which are sequentially outputted by the optical characteristics switching element, to the video display element, wherein light outputted by the video display element is incident on a projecting lens, and a light path from the light source unit to the projecting lens is U-shaped. Consequently, the projection-type video display apparatus becomes compact and has improved contrast.

摘要： A two-dimensional recording head (10) is provided which controls respective windows of a liquid crystal cell array to open and close for light and can hold them in the opened and closed states. A light source (11) is disposed at one side of the head, at the other side of which are disposed an image-forming lens system (15) for exposing a recording medium (16) to an image formed on the head by the opened and closed states of the windows. A controller (17) is provided for controlling the quantity of light which is applied to the recording medium. The image is written into the head by a binary image signal and the exposure is started, with the written image held unchanged. The controller stops the exposure when the quantity of light applied to the recording medium reaches a pretermined value.

摘要： A light source system (200), comprises: a light-emitting device (1) for emitting a first light and a second light in sequence; a beam splitting system (2) with which the first light emitted from the light-emitting device (1) is divided into one beam in a first range of wavelength and the other beam in a second range of wavelength, respectively emitted along a first optical path and a second optical path, and also with which at least a part of the second light emitted from the light-emitting device (1) is emitted along the first optical path; a first spatial light modulator (211) for modulating the beam emitted from the beam splitting system (2) along the first optical path; a second spatial light modulator (213) for modulating the beam emitted from the beam splitting system (2) along the second optical path. The light source system (200) has the advantages of high light-emitting efficiency and low cost. A projection system comprising the aforementioned light source system (200) is also provided.
