摘要： Methods and apparatus are described for retrieving information from a storage medium. A first portion of the surface of the storage medium is exposed to stimulating light which diffuses in the storage medium under a second portion of the surface adjacent the first portion. The second portion of the surface is shielded from exposure to the stimulating light. Stimulated light corresponding to the information is received with at least one detector positioned to receive the stimulated light via the second portion of the surface of the storage medium. The stimulated light is released from the storage medium in response to the stimulating light diffused under the second portion of the surface.

摘要： Methods and apparatus for generating an x-ray image. An object is interposed between a detector and an x-ray source. A grid is interposed between the x-ray source and the object. The grid is exposed to primary x-ray energy generated by the x-ray source, thereby exposing the object to a first portion of the primary energy via the interstices of the grid. A second portion of the primary energy is received with first areas of the detector corresponding to the interstices of the grid. Secondary x-ray energy is received with the first areas of the detector and with second areas of the detector corresponding to the elements of the grid. The secondary energy results from scattering of the primary x-ray energy. Image data are generated by altering data from the first areas with reference to data from the second areas.

摘要： An adjustable apodized lens aperture is described which is constructed using photochromic material. As the excitation energy increases, the aperture constricts so as reduce the amount of light through the aperture. As the excitation energy decreases, the aperture dilates so as increase the amount of light through the aperture.

摘要： An optical system operable to transmit an energy flux is described. A first substantially spherical lens includes first and second substantially hemispherical portions joined at an interface. The interface includes a partially reflective material on a first substantially planar surface of at least one of the first and second hemispherical portions. A second lens has a convex surface and a second substantially planar surface. A portion of the second substantially planar surface of the second lens is secured to the first lens to form an optical axis. The first and second lenses are operable to transmit a first portion of the energy flux along the optical axis. The partially reflective surface is operable to reflect a second portion of the energy flux at an angle to the optical axis.

摘要： A method and apparatus for generating a control signal which corresponds to movement of an object in contact with a first surface are described. The apparatus includes a platen having the first surface. The platen is characterized by a critical angle beyond which light incident upon the first surface is not transmitted. A source of electromagnetic radiation emits electromagnetic radiation through the platen thereby illuminating the object. A detector having a plurality of sectors receives a portion of the electromagnetic radiation diffused by the object and transmitted through the platen beyond the critical angle. The sectors of the detector accumulate charge in response to the incident electromagnetic radiation. Conversion circuitry then converts the charge accumulated in the detector to the control signal, which in a specific embodiment is for controlling the movement of a pointer on a display.

摘要： A solid state image sensor CCD array (10a) has a two block, full-frame, parallel-register structure. The two blocks of the array, each comprised of photosensitive radiation sensors or pixels (20), feed into a single centrally disposed serial read-out register (10b) so as to form one unified photosensitive domain. The read-out register is photosensitive except for two associated narrow clock buses (H1, H2) that are spaced apart so as to only block a minimum of input radiation in any one pixel (22) of the read-out register. Each stage of the read-out register can act as a pixel that is approximately square and that is approximately the same size as the pixels of the two full-frame blocks. In operation, the centrally disposed read-out register can be stationary for a significant first portion of a total frame time (integration period), and then in a latter part of the frame time it can be read out one or more times to provide exposure update information for all of the pixels of the array. Typical examples of applications include advanced histogram-based, or other types of, X-ray exposure optimization. The array avoids the use of an "amplifier corner" that is characteristic of most if not all area image sensors. As such, all four corners of the array can be shaped to suit a particular application. One application of particular interest is for intra-oral dental X-ray imager and system.

摘要： Electronic displays are provided which can reproduce image data with high contrast ratios and a gray scale range comparable to conventional X-ray film viewed on a light box. One such display includes a rear low-resolution LCD or DLP display which projects an image onto a high-resolution LCD display. In such embodiments, the mechanical and optical registration between the two displays is not critical. Therefore, modulation transfer function and distortion of the projection optics are not critical. Accordingly, the brightness of the inventive display can be maximized with high power lamps and high aperture projection optics. Because the display has a high dynamic range, the need for dynamic range compression algorithms is reduced.

摘要： A method of controlling the dynamic range of a CCD or similar device. The method is used in connection with a charge-coupled device or like structure of known construction having a photogate region in which charge is generated at a rate proportional to the intensity of incident electromagnetic radiation. The photogate accumulates charge during a predetermined exposure period. A sink region is disposed to receive excess charge from the photogate region, and the passage of charge from the photogate region to the sink region is controlled by a control gate of the type commonly used for integration control. A second gated region is present for receiving charge from the photogate region for transporting charge therefrom. A potential is applied to the control gate which has a magnitude causing all charge above a certain charge clipping level in the photogate region to pass to the sink region, and the magnitude of the potential is caused to vary during the exposure period according to predetermined function, which may be a non-linear function such as logarithmic. In this way the clipping level varies according to the predetermined function in real time during the exposure period. The total charge accumulated in the photogate region, limited according to the predetermined function, is then transferred to the second gated region at the end of the exposure period.
