    摘要: Stereoscopic effects can be created by binocular parallax. Known stereoscopic display systems show pseudoscopic effects in outer areas of the image viewing position and the viewing position is fixed. To avoid such pseudoscopic effects and/or to change the viewing position stereoscopic displays using parallax barriers with variable pitch length, moving barriers parallel to the display plane, and a polarizing device forming polarized light together with polarizing prisms are provided.

    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: In laser feedback systems of an optical memory the most suitable feedback gain value depends on the type of optical disks used. According to the invention a system and a method is provided which finds by way of an iteration a suitable maximum feedback gain value so that the feedback system does not oscillate. The method consists in starting with a low gain value for driving a laser diode, increasing the gain value by small amounts until an oscillation detecting unit detects that the laser feedback system is oscillating. Then the gain value is reset to the previous value or a little bit more. Then the laser feedback system is again in a non-oscillating area with a suitable maximum gain value. This iteration is performed by a system consisting mainly of a laser diode, a photodiode for detecting the reflected light, and an oscillation detecting unit which controls a gain controller. This gain controller sets the gain on a multiplier which drives the laser driver for the laser diode.
