Abstract: Apparatus for identifying a plurality of given elements read out of an array of elements arranged in lines and columns is described. The apparatus includes a line-rate counter for developing addressing signals and a memory for providing data signals corresponding to the column location of the given elements in response to the addressing signals. A programmable counter counts columns in response to the data signals read out of the memory for providing a signal which corresponds in time to read out of respective ones of the plurality of given elements.

Abstract: Alignment of a plurality of thinned substrate solid-state imagers mounted at the outputs of an optical assembly is accomplished optically, without the necessity to electrically operate the imagers. Light blocking alignment indicia, such as a chevron pattern, are deposited over the electrode structure of the chip. When the imagers are positioned at the optical assembly outputs and light is used to illuminate the imagers electrode structure side, the alignment indicia are visible at the optical assembly input and can be used for alignment of the imagers.

Abstract: Stripe patterns of varying spatial frequency, formed in the top-metalization of a back-illuminated solid-state imager, facilitate on-line measurement of contrast transfer function during wafer-probe testing. The imager may be packaged to allow front-illumination during in-the-field testing after its manufacture.

Abstract: A television camera support for mounting and providing optical alignment between the imaging axes of a lens and an image pickup apparatus. The support is of single-piece construction and generally "L" shaped and includes a vertical portion adapted to receive the camera lens and a horizontal portion adapted to receive the image pickup apparatus. In a preferred embodiment, only the vertical portion of the support is attached to the body of the television camera and the structural rigidity of the camera body near the point of attachment is less than the rigidity of the support, thereby minimizing misalignment of the imaging axes if excessive forces are accidentally applied to the lens.
