Patent number: 8654264Abstract: Laser projection system suitable for commercial motion picture theaters and other large screen venues, including home theater, uses optical fibers to project modulated laser beams for simultaneously raster scanning multiple lines on screen. Emitting ends of optical fibers are arranged in an array such that red, green and blue spots are simultaneously scanned onto the screen in multiple lines spaced one or more scan lines apart. Use of optical fibers enables scanning of small, high resolution spots on screen, and permits convenient packaging and replacement, upgrading or modification of system components. Simultaneous raster scanning of multiple lines enables higher resolution, brightness, and frame rates with available economical components. Fiber-based beam coupling may be used to greatly enhance the flexibility of the system.Type: GrantFiled: October 11, 2006Date of Patent: February 18, 2014Assignee: Magic Lantern, LLCInventors: John P. Callison, Jeffrey S. Pease, Richard W. Pease

Patent number: 7102700Abstract: A laser projection system preferably for use in commercial motion picture theaters and other large screen venues, including home theater, uses optical fibers to project modulated laser beams for raster scanning on the screen. The emitting ends of the optical fibers are arranged in an array such that red, green and blue spots are simultaneously scanned onto the screen in multiple lines spaced one or more than one scan line apart. The use of optical fibers for laser beam projection eliminates the need to use complex optics, and enables the scanning of small, high resolution spots on the screen. The use of optical fiber also permits convenient packaging and permits replacement, upgrading or modification of the system components. The scanning of multiple lines simultaneously is accomplished by reordering the video signal with a microprocessor controller component to write lines in a sequence after repeated vertical sweeps to form a complete picture.Type: GrantFiled: September 2, 2000Date of Patent: September 5, 2006Assignee: Magic Lantern LLCInventors: Richard W. Pease, Jeffrey S. Pease, John P. Callison

Patent number: 5136426Abstract: A high efficiency light projection apparatus using lasers that optimize all available power output from two lasers to provide a balanced color display is disclosed. The light projection apparatus comprises two laser and light separation means to produce separate red, green and blue light beam components. A combiner cube is provided for combining the blue light beam component of one of the lasers with the blue light beam component of the other laser. Also provided is a second combiner cube for combining a portion of one of the lasers green light beam component with the other lasers green light beam component which combined components are transmitted to a dye laser to provide a red light beam component.Additionally, a light projection apparatus is disclosed that provides convenient access by the operator and presents an overall narrower configuration for the projector for transportation, installation and alignment purposes.Type: GrantFiled: February 27, 1991Date of Patent: August 4, 1992Assignee: Advanced Laser Projection, Inc.Inventors: Paul A. Linden, Richard W. Pease

Patent number: 5097480Abstract: The invention comprises a laser light source for a raster laser display. The laser light source comprises a laser cavity, a lasing medium within the cavity, a lasing light source and a series of mirrors within the cavity arranged to reflect the beam of laser light repeatedly through the lasing medium. An acoustic modulator is included having an acoustic medium within the path of the beam within the cavity. Video information on each pixel of the display is converted to an RF signal and fed to a piezoelectric crystal which is coupled to the acoustic medium. The acoustic medium is arranged within the laser cavity with respect to the incident laser beam such that, in response to the acoustic information, the laser beam is either directed towards the screen, or when not needed for the display is directed towards one of the mirrors such that the beam can continue to propagate through the lasing medium.Type: GrantFiled: January 24, 1990Date of Patent: March 17, 1992Assignee: The MITRE CorporationInventor: Richard W.
