Abstract: Aligning a cut-to-size (off-wafer) pixilated micro-grid polarizer to a ready packaged imaging sensor having multiple pixels involves minimizing a separation distance between the two units and then aligning respective corresponding pixels of the pixilated micro-grid polarizer with the pixels of the imaging sensor using optical signals as position feedback during the alignment process. Once the alignment has been achieved, the micro-grid polarizer may be affixed to the imaging sensor, for example using optical epoxy glue.

Abstract: Micro-lenses are formed on the surface of a semiconductive circuit through a plurality of processing stages. In each stage, an alternate lens placement pattern is imparted onto micro-lens suitable material. Unwanted material is removed and micro-lenses are formed from the remaining material. Subsequent stages are applied until all desired micro-lenses in a structure are defined and formed from alternate placement patterns.

Abstract: A camera is described which is capable of meeting the United States standards for high definition television (HDTV). The camera produces a display of 1280 pixels by 720 pixels at a rate of 60 frames per second. In the preferred embodiment, there is provided, as an image sensor, a frame transfer three phase buried channel CCD capable of shifting the charge from an imaging region to a storage region within a brief blanking period provided by a shuttered lens. The image sensor has an arrangement of spaced electrodes which are electrically connected to shunts in the image sensor to transport charge, but are also arranged in the imaging region such that the geometry of the electrodes within each of the plurality of pixels is similar and thereby reduce the resistance present during shifting the charge from the imaging region to the storage region.

Abstract: A charge injection imaging device comprises low bandwidth, low noise performance column amplifiers serially connected to respective charge coupled device storage lines. Image and/or noise defining electronic information signals are retrieved from the charge injection imaging device by way of the amplifiers and storage lines in a manner which provides image defining electronic information signals from which the noise defining electronic information signal portions have been automatically subtracted for each succeeding photosensitive element of the device. The subtracted noise portions include both KTC noise and fixed pattern noise which are normally inherently associated with the image defining electronic information signals retrieved from the charge injection imaging device.
