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: 8636367Abstract: The power and response curves of one or more beams or primaries of beams of a laser projection system illuminating an image on a viewing surface are controlled to desired characteristics during exhibition by monitoring the scanning beams in real time by using at least part of the horizontal blanking time during the scanning of a motion or still image to project a test pattern with one or more of the beams onto a sensor or sensors. The system and method permits real-time balancing and maintenance of the response curves and power levels of each of the beams, and of primary beams of combined beams, to desired targets so as to produce a display field without artifacts and at desired brightness on the viewing surface.Type: GrantFiled: October 17, 2011Date of Patent: January 28, 2014Assignee: Magic Lantern, LLCInventors: John P. Callison, Jeffrey S. Pease, Gordon L. Elliott

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
