摘要： A private stereoscopic display is provided which has only one stereoscopic viewing position and does not show pseudoscopic images in areas outside the viewing position. On top of the display there is provided a first lenticular lens sheet followed by a prism array sheet and in general by a second lenticular lens sheet. Lens stripes are provided for rows of pixels, consisting normally of two rows of pixels for the left and right image. Two separate side lobes of the light rays generated by the first lenticular lens sheet. The individual lens pixel array arrangement are separated by barriers from each other. Because of those barriers only the main lobe of the light emating from the display is maintained, so that because of the prism array sheet and the second lenticular lens sheet main lobes for the left image are focused in a left image viewing point, whereas main lobes for the right image are focused in a right image viewing point.

摘要： Known LCD projectors, used for example in TV sets, can only be manually adjusted for the compensation of the changing color spectrum of the lamp due to its aging process. An LCD projector according to the invention further comprises an image sensor to measure the light intensity of the lamp. In a color adjusting circuit the image color is compensated as a function of the measured signal by controlling the LCD valve.

摘要： A multi beam track system and method is used for the retrieving of information stored in optical memories like optical disks. The information carrying beams reflected on the surface of such a optical disk results in spots on the surface of a detector array. Because these beams are very close to each other, the resulting spots tend to overlap so that cross talk conditions between neighboring channels occur. As result the S/N ratio becomes worse. According to the present invention a plurality of laser beams arranged in a row is used, where the laser beams are linear polarized and the polarization of neighboring beams differ by 90.o slashed., i.e. neighboring laser beams have perpendicular linear polarization. After reflection on the surface of the optical disk the row of reflected laser beams is separated into two rows by an separating means which is polarization dependent so that beams are separated in space according to the polarization. Such a separator can be a polarizing beamsplitter or a birefringent prism crystal. As a result two spacially separated rows of laser beams are achieved, which can be detected by two separate detectors. As result no overlap between neighboring spots occurs on the surface of the detectors, resulting in the elimination of crosstalk.
