Spatial 3d sterioscopic intraoral camera system background

A method for creating intraoral cavity spatial 3D images for stereoscopic rendering and display comprising the steps of:

• providing dual side-by-side camera CCD subassemblies, each subassembly having an optical path through a lens disposed to direct specified band spectrum light to a CCD;
• optically directing image light through a subassembly optical or pin hole lens, with light image disposed to impinge on the CCD by subassembly tilt or shift with respect to each other;
• converging optical paths of subassemblies to achieve stereoscopic left-right image by tilt, tilt range of between 1° to 5° off the surface mount plane, or shift, shift gap symmetrical with the duel subassembly centerline of between 0.5 mm and 5.0 mm, onto the CCDs;
• focusing the optical paths from the lens to the CCDs by including a focal gap of between 0.01 and 3.0 mm each subassembly;
• surrounding each subassembly with an array of LEDs;
• surface mounting each subassembly on a motherboard supporting electronic components for processing the daughterboard signals and LEDs;
• integrating processing electronic components to frame grab CCD signal images and synchronously output images to frame formats and
• embedding software instructions in the form of device logic stored in component memory for enabling the CCD signal image output, under control of a electronic component processor, to format the signal images for wireless transport to remote processing system for storage and display in 3D Line Sequential Left-Right Multiplexed Spatial Stereoscopic format,
• whereby spatial 3D intraoral images are converged and captured by the duel subassemblies for processing and display in stereoscopic presentation and viewing.

A spatial 3D stereoscopic intraoral camera system comprising:

• processor;
• memory;
• wireless component;
• dual side-by-side camera sensor CCD subassemblies;
• the sensor subassemblies each having an optical path through a lens disposed to direct light to a CCD embedded in a daughter board;
• the duel side-by-side subassemblies each having a CCD imaging chip converging optical paths of subassemblies by tilt, tilt range of between 1° to 5° off the surface mount plane, or shift, shift gap symmetrical with the duel subassembly centerline of between 0.5 mm and 5.0 mm, for focus control to achieve the stereoscopic convergence;
• the CCDs operatively connected and mounted on daughterboards with a lens focal gap of between 0.01 and 3.0 mm each;
• each subassembly surrounded by a programmable logic for frequency sweep through an array of LEDs with source light spectrum spanning from UV to Near Infrared;
• the LED array source light disposed to enter a beamsplitter in the subassembly adjacent to the lens;
• each beamsplitter refracted incoming light from the LEDs to a reference leg optical path normal to the incoming light and with a mirror on the reference path end reflecting reference beam back to beamsplitter and bending toward the subassembly lens;
• each LED between the beamsplitter mirror and the lens centerline positioned in a symmetric pattern LED array emitting Near Infrared light from a transparent surface mounted LED package;
• each beamsplitter having a straight through optical path for illumination and reflected image light recombining with reference light on route to the subassembly lens;
• each subassembly surface mounted on a motherboard supporting other electronic components for processing the CCD signals and LEDs emissions and
• software instructions in the form of device logic stored in memory for enabling the device, under control of the processors to format the CCD signal images for wireless transport to remote processing system for storage and rendering in 3D Line Sequential Left-Right Multiplexed Spatial Stereoscopic format,
• whereby spatial 3D intraoral images are converged, captured and bundled by the duel subassemblies for processing and display in stereoscopic rendering and viewing.
