Abstract: An improved pixel design for a CMOS image sensor with a small feature size is described. In conventional image sensors of this type, the quantum efficiency is typically reduced as a result of the decreased thickness of the top n-type layer of the photodiode and the presence of an intervening p-type layer which is higher doped than the substrate. In the pixel design of the invention, the higher doped p-type layer underneath the photodiode is omitted while barrier regions channel the carriers generated by the impinging radiation towards the top n-layer of the photodiode. A high quantum efficiency is thereby attained in spite of a shrinking feature size. The novel pixel design can also incorporate anti-blooming protection.

Abstract: Apparatus and method for making a plurality of substrates laminated on two sides by applying a plurality of laminate sheets to corresponding plurality of substrates. The apparatus includes a lamina supply member capable of holding a supply of lamina from which successive sheets of lamina can be cut. One or more cutters are disposed in the apparatus such that the cutters are capable of cutting through the lamina to provide successive sheets of laminate. One or more heaters are provided for bonding sheets of laminate to corresponding sides of a substrate whereby the corresponding top and bottom laminated substrate is formed. The supply of lamina is characterized by a current leading edge. The supply of lamina is cut through along a cutting line at a predetermined distance from the current leading edge of the lamina. This provides a first sheet of laminate having a trailing edge at the cutting line. Cutting also provides the lamina supply with a successive leading edge at the cutting line.

Abstract: An actuator device for providing a focusing mechanism in an optical printer or optical recording device. The focusing optics are housed in a lens barrel which is maintained in position within a cylindrical winding of electrical wire by means of two diaphragm springs at the ends of the barrel. Movement of the barrel and the optics is affected by passing a current through the cylindrical winding to produce a longitudinal force on a permanent magnet secured to the lens barrel.

Abstract: An optical storage system suitable for optical storage and retrieval of information using a storage medium comprising a substrate, an active layer for retention of the data, and an overlying optical layer, or layers for double-sided. The optical layer serves to produce an evanescent field in or adjacent to the active layer in response to an incident beam of radiation. The evanescent field is frustrated or attenuated by the data in the active layer and produces a signal.

Abstract: An optical system is disclosed wherein an illumination device is used to project colored light into a lens and focus through a spatial light modulator onto a photosensitive medium wherein the illumination device is configured so as to produce a uniform light distribution through the use of an aperture stop, a symmetrical placement of solid state light sources such as LEDs, or by LEDs fabricated such that the top surface emitting the colored light is not obstructed by an electrode or contacts connecting the light-emitting diode to a current source. Such a configuration is accomplished by providing a substantially transparent attachment layer that may include an opaque conductive material, but preferably includes transparent conductive particles that, in combination, attach and electrically connect the LED to a first electrode disposed upon a substrate.

Abstract: A system operative with photon tunneling microscopy presents an image on a two-dimensional display which is perceived as a three-dimensional presentation by a person viewing the display. An optical image of the subject produced by the microscope is scanned by means of a television vidicon which converts the optical signal to an electric signal representing depth of a surface feature. The electric signal is outputted to the display wherein the image is presented as a set of line scans parallel to the horizontal axis of the display, and wherein the magnitude of the electric signal is plotted on the vertical axis of the display. A variable delay is introduced to be either increased or decreased stepwise between successive ones of the line scans. This results in a tilting of the presentation to the right or the left. Two tilted views are presented simultaneously, one to one eye and one to the other eye of an observer, to give a perception of a three-dimensional view.

Abstract: A spatial light modulator for use in a optical printer where the spatial light modulator includes a plurality of cells, having a shape that is defined to decrease artifacts in an image produced on a recording medium by the optical printer. The shape of the plurality of cells merges a portion of the optical radiation passing through an individual cell of the spatial light modulator with optical radiation from that of adjacent cell to form a pixel on the recording medium. In one implementation each of the cells of the spatial light modulator independently modulate the optical radiation so as to print horizontally-displaced pixels. When LEDs are used as the colored light source, the light is either first diffused to minimize shadows from electrical contacts on the LEDs, thus removing linear artifacts in the image.
