摘要: A single projector and a laser radiation deflecting means enable laser generated images to be projected onto a screen together with a laser pointer. A first laser beam polarized in a first plane and a second laser beam polarized in a second plane is projected into a polarizer cube wherein the first laser beam is reflected to a record medium to record images thereon and the second laser beam is transmitted through the polarizer cube. Polarization and deflecting means located in the path of the transmitted second laser beam changes the polarization of the second laser beam to the polarization of the first laser beam and reflects the second laser beam back into the polarizer cube wherein the second laser beam is reflected in a direction opposite to that of the first laser beam to enable the second laser beam to function as a pointer. By backlighting the record medium with illumination radiation polarized in the second plane, the images recorded on the record medium can be projected onto a screen together with the laser pointer. Illumination radiation polarized in the second plane is obtained from unpolarized illumination by focusing the unpolarized illumination radiation into a polarizer cube to convert the single beam of unpolarized radiation into a first beam of radiation polarized in the second plane and a second beam of radiation polarized in the first plane. By changing the polarization of the second beam of radiation to polarization in the second plane, both the first and second beams of polarized, illumination radiation can be utilized to backlight the record medium to project the image(s) recorded therein.

摘要: A projected light beam video image display system. The displayed scene is presented in contiguous scene parts which form a single scene. Modulated beams for each scene part are generated and simultaneously scanned in the pattern of a TV raster for each. The beams are projected onto a viewing surface through a beam separator which separates the beams such that each beam scans a separate scene part in appropriate location on the viewing surface to form the single scene.

摘要: Technique for generating scanned video signals for a viewed scene by scanning a beam of white light across the scene to be viewed and detecting the amounts of light reflected from the scene in each three spectral regions corresponding to the primary colors. The beam of white light comprises four monochrome components. Three components comprise beams of monochrome light corresponding to the three primary colors, while the fourth component is a monochrome beam of light having a color intermediate two of the primary colors, and intermediate adjacent color distinguishable pigment reflectance fall-off regions.

摘要: A high-speed, permanent recording, multicolor projection display system in which the beam of a pulsed Argon laser is selectively deflected and focused to burn the desired images in a metalized film record medium which is back-illuminated for projecting the recorded images as they are produced. A channel selector polarizes the laser beam in either of two planes; each polarized channel is then selectively deflected and is focused through a dichroic/polarizer cube that transmits one channel and reflects the other channel to the metalized films in the focal planes where images are formed by the thermal action. Simultaneously with the recording action, the images are projected by the use of white light that is split into two colored light beams by a second dichroic cube and is reflected to backlight the images in each of the metalized films. The projected beams then pass back through the first dichroic cube where they either pass directly, as colored images, to the projection lens system, or are combined into white images before entering the projection lens system. Colored filters may be inserted into either or both of the projection lamp beams to produce various colored images.
