LIGHTWEIGHT RIGID MIRROR AND A METHOD OF PRODUCING A LIGHTWEIGHT RIGID MIRROR
A mirror body, a mirror array, and a method of producing a mirror and a mirror array are provided. The mirror body can be formed of a rigid foam and has a front surface with a shape adapted to reflect light that originates in a projector of a simulator. A block of the rigid foam may be machined to form the mirror body. A reflective material is positioned over the front surface to reflect light from the projector. In embodiments, the reflective material is a sheet of a metalized film. In embodiments, the reflective material is applied to the front surface in a first state and subsequently changes to a second state. The mirror array may be formed of two or more mirror bodies. In embodiments, a seam between adjacent mirror bodies is covered with the reflective material.
Universally adjusting ultra short throw projector credenza
Universally adjusting Ultra Short Throw (UST) projector credenza having a sliding UST compartment allowing for the cabinet to lie flush or near flush with a forward wall. The UST compartment expands out to a predetermined position to accommodate projecting images onto 100+ inch screens above. Each UST compartment comes with a cross-drilled and ventilated floating shelf that can be adjusted in three dimensions withing the compartment to allow adjustments. Ventilation holes in the shelf aerate the projector without obstructing ventilation. The UST compartment may have a low iron pane of glass over the projector to make it more discrete and hidden, but does not obstruct the image or color of the projected image passing through it in any way.
Remote 6P laser projection of 3D cinema content
A 3D laser projection systems and methods are disclosed herein. A laser projection system includes a left projector head and a right projector head, wherein a first video projected onto a movie screen by the left projector head has a first polarization and a second video projected onto the movie screen by the right projector head has a second polarization different from the first polarization. The laser projection system can include a laser light generator located a first defined distance away from the left projector head and a second defined distance from the right projector head and coupled to the left projector head and the right projector head with fiber optic cables that transmit light from the laser light generator to the left projector head and the right projector head. The laser light generator includes a laser diode configured to output light and to transmit it to the fiber optic cables.
Large format cinema screen and projection system
A cinema theater includes a seating area, a curved screen in front of the seating area and at least one projector. In one aspect, the seating area is preferably a stadium seating area and the at least one projector is positioned behind and above the stadium seating area. In another aspect, the curved screen has a center point and the at least one projector is mounted at an angle of incidence to the center point of the screen of between ±5° horizontal and ±5° vertical. In yet another aspect, the seating area that has an upper seating area and a lower seating area and the at least one projector is positioned at the front of the upper seating area.
METHOD AND SYSTEM FOR CREATING WIDE-SCREEN PICTURE-DOMINANCE EFFECT IN A CONVENTIONAL MOTION-PICTURE THEATER
A system and method are disclosed for exhibiting wide-screen motion pictures, including in multiplex-style theaters, with an immersive, picture-dominance effect not previously obtainable in such theaters. The invention uses a zero-gain or nominal-gain curved screen to accommodate a wide-screen presentation, and a digital projector capable of delivering 14 to 22 foot-lamberts of light to the screen. The invention can support any theatrical aspect ratio for presentation, including the widest in use, 2.76:1. To eliminate image distortion, the invention uses warping software to correct the image for the geometry of the auditorium and the shape of the screen. This correction is established for every aspect ratio that will be accommodated in the auditorium in which the invention is installed, and aspect ratios can be changed to display content with different aspect ratios during a program.
DISPLAY DEVICE
Implementations of a display device of the present disclosure include a transparent light guide plate in which a light guide plate image that is an original video of an aerial image is formed on a bottom portion, a light source configured to emit light L from a side portion of the light guide plate toward the inside of the light guide plate, a polarization beam splitter disposed in parallel with the light guide plate and above the light guide plate, a λ/4 plate disposed below the light guide plate, and a retroreflective member disposed in parallel with the light guide plate and below the λ/4 plate, which retroreflects the light guide plate image to display the aerial image.
Polarizing preserving front projection screen with protrusions
A projection screen for diffusing illumination light into a range of viewing angles is formed by depositing a coating on a substrate. Within the coating are particles having an average particle height. Protrusions at least two microns higher than the average particle height may be substantially uniformly distributed over the screen. In some embodiments, each protrusion may be no closer than 80 microns to another protrusion.
Calibration step for use in connection with method and system for creating wide-screen picture-dominance effect in a conventional motion-picture theater
A calibration step is disclosed for use with a system and a method for creating a wide-screen picture-dominance effect in an auditorium located in a motion-picture theater. This is accomplished by an operator viewing a test image or images of horizontal and vertical lines projected onto a deeply-curved screen in said auditorium and adjusting the projection of said test image or images until the horizontal and vertical lines in said image or images appear straight and orthonormal, with the result that viewers watching motion pictures in said auditorium will observe images that appear wider than the physical confines of the auditorium in said theater.

Method and system for creating wide-screen picture-dominance effect in a conventional motion-picture theater
A system and method are disclosed for exhibiting wide-screen motion pictures, including in multiplex-style theaters, with an immersive, virtual reality picture-dominance effect not previously obtainable in such theaters. The invention uses a zero-gain or nominal-gain curved screen to accommodate a wide-screen presentation, and a digital projector capable of delivering fourteen foot-lamberts or more of light to the screen. It can support any theatrical aspect ratio for presentation, including 2.76:1. To eliminate image distortion, the invention uses mapping software to correct the image for the geometry of the auditorium and the shape of the screen. This correction is established for every aspect ratio displayed in the auditorium in which the invention is installed, and aspect ratios can be changed to display content with different aspect ratios during a program. The images delivered to viewers through the invention deliver the full benefit of the native aspect ratio in which they are displayed.
