摘要： An apparatus and a method for calibrating and normalizing a stereolithographic apparatus so that a reaction means directed by a positioning means supplied with positioning means information may be positioned accurately on a designated surface of a working medium. One or more sensors fixed in location with respect to the designated surface of the working medium are utilized to correlate positioning means information with specific locations on the designated surface of the working medium. Other locations intermediate the specific locations may then be determined by the technique of linear interpolation.

摘要： An improved stereolithography system for generating a three-dimensional object by creating a cross-sectional pattern of the object to be formed at a selected surface of a fluid medium capable of altering its physical state in response to appropriate synergistic stimulation by impinging radiation, particle bombardment or chemical reaction, information defining the object being specially processed to reduce curl and distortion, and increase resolution, strength, accuracy, speed and economy of reproduction even for rather difficult object shapes, the successive adjacent laminae, representing corresponding successive adjacent cross-sections of the object, being automatically formed and integrated together to provide a step-wise laminar buildup of the desired object, whereby a three-dimensional object is formed and drawn from a substantially planar surface of the fluid medium during the forming process.

摘要： A lamp, a film guide, and a photosensitive detector are combined into an optical system contained in a portable device that generates electrical signals representing images recorded on motion picture film. The film guide has a surface proximate to the motion picture with an aperture therein through which light from the lamp passes to image the film on the photosensitive detector. A digital processor, which is electrically connected to the photosensitive detector processes an electronic signal output by the photosensitive detector. To provide compactness, the optical system has a folded path comprising three segments each separately mounted on a different surface. The first segment includes the lamp, the second includes the film guide, and the third includes the photosensitive detector. An optical detector positioned so as to receive light from the lamp enables adjusting the device when the device is moved to a location where the temperature and other environmental conditions change. This configuration also finds use when the device is located in an environment whose temperature remains consistently hot.

摘要： A digital processor to synchronize ancillary information with film images during a film conversion session is described. The ancillary information includes metadata information and audio information. The digital processor advantageously processes the ancillary information at a speed to support faster than real-time film conversion. The ancillary information can come from various sources and in various forms. Information from analog sources is digitized for processing using digital technology. A pitch adjuster frequency shifts digitized analog signals and digital input signals to achieve a selected data rate that matches the rate of film conversion. Digitally encoded input data can be decoded and re-encoded to achieve the selected data rate. A formatter manipulates the ancillary information at the selected data rate to conform to a standard format and combines the formatted ancillary information with film images conforming to a standard motion picture format.

摘要： An apparatus and a method for correcting for drift in production of objects by stereolithography is disclosed. A beam sensor comprising a pinhole in a plate and a photodector behind the pinhole is used to obtain the apparent position of the beam at calibration time and subsequently. A comparison between the prior and present apparent position of the sensor is made in order to determine a drift error correction term to be used to compensate for drift and thereby improve the accuracy and pointing repeatability of the scanning mechanism.

摘要： An illumination subsystem, a film guide subsystem, and an imaging subsystem are combined to form an optical system for a film conversion device which projects an image recorded on film onto the at least one optical sensor. The illumination subsystem comprises a lamp. The film guide subsystem comprises a film guide wide enough to support film moving thereover and having an aperture that permits passage of light from the lamp through the film. The imaging subsystem comprises an imaging lens and an optical sensor situated so as to receive the light passing through the aperture and the film. The three subsystems together have an optical path that is folded substantially into the shape of a “U”. This folded arrangement is achieved by placing optical beam bending elements in the optical path of the film conversion device between the illumination subsystem and the film guide subsystem, and between the film guide subsystem and the imaging subsystem. This folded arrangement of the components of the optical system permits the components of the illumination subsystem and the imaging subsystem to be mounted back-to-back on the same support structure within the film-to-video module. Consequently, the optical system requires less space than is required without the folding of the optical path.
