In a readout bus architecture having a first column, a readout means is coupled to a photodetector and configured to transfer charge from the photodetector. A select means is coupled to the photodetector and is configured to transfer charge from the photodetector. An address circuit is coupled to the first column through the select means and is configured to generate and decode an address and turn on the select means for the first column if the address matched the first column and if the address circuit received a corrected enable signal indicating that the first column is not defective. A correction circuit is coupled to the address circuit and is configured to generate the corrected enable signal indicating that the first column is not defective if the correction circuit determined that the first column is not defective.

Method and apparatus for eliminating image artifacts due to defective imager columns and rows

A method of manufacturing an imaging subsystem is provided. The method includes manufacturing an image sensing device including a unique identifier. The image sensing device is incorporated into an imaging subsystem. The imaging subsystem is operated and characterization parameters of the image sensing device operation are determined based thereon. The characterization parameters are associated with the unique identifier in a repository of characterization parameters that is separate from the imaging subsystem.

Methods for manufacturing and testing image sensing devices

A color-separation prism assembly comprises first, second and third prisms. The first and second prisms have entrance surfaces, exit surfaces, and partially-reflecting surfaces, wherein the entrance surface of the second prism is separated by an air gap from the partially-reflecting surface of the first prism. The third prism has an entrance surface and an exit surface, wherein the entrance surface of the third prism is adjacent to the partially-reflecting surface of the second prism. The first prism has a cut-out serving as a flare-stop stop, and providing relief so as to allow the entrance surface of the third prism to slide across a plane disposed over the cut-out into a volume defined by the cut-out. The plane is formed as an extension of the partially-reflecting surface of the first prism. An optical axis passes through the first, second and third prisms. The optical axis passes at normal angles through the entrance surface of the first prism, and the exit surfaces of the first, second and third prisms. The partially reflecting surfaces each have angles-of-incidence of less than,&deg; relative to the optical axis.

Digital data bits are stored as discrete-level reflection microholograms in a multi-depth digital optical data storage system. Reference and signal beams are incident in a counterpropagating geometry on opposite faces of a tape. The reflection microholograms are stored at the coinciding focus of the reference and signal beams. The holograms are stored at the diffraction limit of high-N.A. optics, and have relatively high grating frequencies and small sizes. Dynamic aberration compensators correct for the depth-varying spherical aberration imparted to the beams by the medium. Multiple mutually-incoherent lasers are used for parallel storage and retrieval to increase data transfer rates. Achievable densities and signal-to-noise ratios are substantially higher than for index-perturbation or transmission hologram storage methods.
