Abstract: An apparatus for presentation of apparent three-dimensional images without special viewing glasses is disclosed. A projection system projects right and left stereo images from a stereoscopic slide so that the right stereo image and the left stereo image become superimposed relative to one another on a viewing screen. The viewing screen comprises light transmissive slit-raster members and a light diffusion member. The viewing screen is adapted to allow the right and left stereo images to pass between the opaque raster members and be perceived only by the right and left eyes, respectively, of the viewer as the left image formed in a raster-like manner on the diffusion member is blocked by further opaque raster members and prevented from being perceived by the right eye and the right stereo image also formed in a raster-like manner on the diffusion member is blocked by the further opaque raster members and prevented from being perceived by the left eye.

Abstract: This invention relates to the production of 3-D TV or motion pictures using novel electro-opto-mechanical devices. The system utilizes a continuous panning camera. The images are viewed through photopic and scotopic filters incorporated into a viewer or special lenticular or raster screen. Use of the screen replaces the viewers.

Abstract: Apparatus and a method for adhering a flexible soft polarizing film to a curved surface, such as the convex surface of a prescription eyeglass to be made into a polarizing lens is disclosed. The method involves glass-casting, and preformation of the film in a manner calculated to have a minimum hardening/drying effect. Air is excluded during lamination without the need for a vacuum and the attendant complications.

Abstract: A method and apparatus of applying a polarizing film to a curved lens such as a polarizing prescription lens is disclosed. Mounting of the film on a specialized template allows for convenient drying and rewetting.

Abstract: This invention provides a high efficiency polarized light source and system for the projection of 3D motion pictures adaptable to a standard motion picture projector device. The projected light beam is compressed into a shape more nearly approximating the aperture shape so that substantially less than 40% of the light is lost at the gate.

Abstract: This invention relates to a system for photographing, presenting and viewing 3D images, in which a set of mutually extinguishing multichrome "C" and "D" filters in spectacles is utilized to cover a first eye with a "C" blue filter and a second eye with a "D" orange filter. The "C" blue filter transmits at 400 to 500 nm.The "D" orange filter absorbs from 400nm to 500 nm and transmits from 500 nm to 700 nm. Standard color film may be utilized to photograph stereo image pairs of the subject in which a first image is in blue, and a second image is in orange. With this system, one eye transmits a first stereo image in blue via retinal receptors to the brain and the other eye transmits a second stereo image in orange via other retinal receptors to another portion of the brain. Thus, the stereo images are separated according to their 3-dimensional displacements and color. The brain integrates the color and 3D information received by the two eyes to produce a full 3D color picture.

Abstract: Stereo pairs which have been printed on a single film strip are directed and focused upon a screen by an attachment for a standard motion picture projector. The images are overlapped and polarized at right angles to the other upon the screen by an optical device having abutting elements. The stereo pairs on the film are separated by an opaque band to define the edges of the projected image and mask element abutment. Indicia marks may be provided on the film to enable the positioning of the right and left images on the film in the gate to avoid pseudo stereo projection. A film format for stereo pairs uses a dark bar centered at the aperture on the film or gate.

Abstract: This invention relates to a reflex camera device having a single lens for the photography of right and left images from an object space transmitted as first and second light ray bundles from two positions separated by an interocular distance onto a single frame of a single film strip; a first exterior means for distinguishing from each other the first and second light ray bundles; a single frame aperture; a second means near the image plane to separate the first and second light ray bundles from each position respectively into right and left adjacent images onto the single frame; means to control convergence, focus and interocular distance; and a reflex viewer containing a third distinguishing means near the image plane to enable the simultaneous viewing and photographing of right and left adjacent images; and optionally an indicium marking means for said film strip at the side of the frame line.

Abstract: Stereo pairs suitable for motion picture projection are derived from conventionally taken motion picture film by selection of frames and rearrangement thereof in side by side relationship upon a continuous strip of motion picture film. The pairs so prepared may be incorporated into film containing conventionally photographed stereo frames to provide a compatible system for 3-dimensional motion picture projection.

Abstract: This invention relates to a system for photographing, presenting and viewing 3D images, in which a set of mutually extinguishing multichrome A and B filters in spectacles is utilized to cover a first eye with an "A" green filter and a second eye with a "B" magenta filter. The "A" greenfilter transmits at 450 to 580 nm and peaks about 515 to 540 nm. The "B" magenta filter absorbs from 475 nm to 575 nm. Standard color film may be utilized to photograph stereo image pairs of the object in which a first image is in green, and a second image is in red and/or blue. With this system, one eye transmits a first stereo image in green via retinal receptors to the brain and the other eye transmits a second stereo image in red and/or blue via other retinal receptors to another portion of the brain. Thus, the stereo images are separated according to their 3-dimensional displacements and color. The brain integrates the color and 3D information received by the two eyes to produce a full 3D color picture.
