Patent number: 12348911Abstract: Systems for displaying images in a cinema setting can include components to reduce screen-door effect. The systems can include an array of light emitting sources or other active sources of light. In one example, the light emitting source emit pixels of light to a projection lens to project an image represented by the projection lens and a baffle and an aperture stop can block part of the light from the sources that exceeds an allowable cone angle of acceptable of the system. In another example, a display includes the array of light emitting sources and additional elements, such as diffuser elements, positioned in front of the array of light emitting sources.Type: GrantFiled: December 21, 2023Date of Patent: July 1, 2025Assignee: IMAX CORPORATIONInventors: Barry Silverstein, Steen Svendstorp Iversen, Steven Charles Read, Denis Tremblay, Anton Leonard Baljet, Jesse Donald McMullen-Crummey, Andrew F.

Patent number: 10073328Abstract: Chromatic aberration can be reduced and extreme projection angles can be allowed in a projection system by modifying one color channel of light having a wavelength bandwidth with image data to produce imaged light, causing the imaged light to spread angularly when displaying the imaged light through an optical distorting element onto a screen, and reducing angular spread of the imaged light exiting the optical distorting element by adjusting the wavelength bandwidth.Type: GrantFiled: October 13, 2016Date of Patent: September 11, 2018Assignee: IMAX CorporationInventors: Steen Svendstorp Iversen, John W. Bowron

Patent number: 7289272Abstract: An optical system includes a primary lens group having a central beam path therethrough and including a front lens group and a rear lens group. An anamorphic lens group lies on the central beam path and is positioned between the front lens group and the rear lens group. The anamorphic lens group includes at least one optically powered anamorphic lens that has different enlargements of a light beam along different axes perpendicular to the central beam path. The anamorphic lens group may be mounted on structure that allows it to be removed from the central beam path. An image transceiver is either an image source that directs a light beam through the primary lens group and the anamorphic lens group, or is an image receiver that receives a light beam through the primary lens group and the anamorphic lens group.Type: GrantFiled: September 16, 2005Date of Patent: October 30, 2007Assignee: Raytheon CompanyInventors: John W. Bowron, Reginald Peter Jonas

Patent number: 6644813Abstract: A 4-prism color management device (600) comprised of first, second, third, and fourth prisms (610, 612, 614, 616). The first prism (610) is adjacent to the second prism (612) with an air gap (620) interposed therebetween, the second prism (612) is adjacent to the third prism (614) with an air gap (624) interposed therebetween, and the third (614) prism is adjacent to the fourth prism (616) with an air gap (626) interposed therebetween. The first prism (610) includes a first surface (630) for inputting and outputting a beam of light. The second prism (612) includes a first dichroic surface (642) mounted at a first angle (&bgr;) with respect to the first surface (630) for reflecting light of a first color and for transmitting light of a second color and light of a third color. The third prism (614) includes a second dichroic surface (644) mounted at a second angle (&khgr;) with respect to the first surface (630) for reflecting light of the second color and for transmitting light of the third color.Type: GrantFiled: January 4, 2002Date of Patent: November 11, 2003Assignee: Raytheon CompanyInventor: John W.

Publication number: 20020186366Abstract: An optical bench for processing laser light in a laser system, including an optical bench housing, steering optics mounted within the optical bench housing for directing the laser light in a path from a laser light input to an output, and a first mechanism for monitoring power output of the laser light regardless of shifts in wavelength of the laser light. The steering optics includes a sampling filter mounted to the optical bench housing and positioned in the path of the laser light, wherein a first portion of the laser light is reflected to the output and a second portion of the laser light is transmitted to the first mechanism.Type: ApplicationFiled: June 8, 2001Publication date: December 12, 2002Inventors: Robert M.

Patent number: 5192980Abstract: A scanning optical microscope or mapping system for spectrally-resolved measurement of light reflected, emitted or scatttered from a specimen is disclosed, in which the spectrally-resolving element is integrated into the detection arm of the microscope or mapping system to result in good photon collection efficiency as well as good spectral and spatial resolution. A confocal version of the microscope is disclosed which will be of particular interest in fluorescence microscopy, and the non-confocal mapping system will be of particular interest in photoluminescence mapping of semiconductor wafers.Type: GrantFiled: June 26, 1991Date of Patent: March 9, 1993Assignee: A.
