Abstract: A high-sensitivity photometer/radiometer uses a single-pixel charge-injection-device (CID) light-sensitive sensor, and associated circuitry for: non-destructively reading-out the sensor charge level; for summing signals proportional to the charge level signal; and for then displaying the level. With cooling of the CID sensor, the sensitivity of the photometer can be sufficient to read incident flux levels on the order of several photons per second.

Abstract: An array of charge storage devices each including a pair of closely coupled conductor-insulator-semiconductor cells, one a row line connected cell and the other a column line connected cell, is provided on a common semiconductor substrate. Readout of the charges stored in a row of devices is accomplished by transferring the charge in each of the devices of the selected row of devices in one direction between the row line connected cell and the column line connected cells of a device in sequence and sensing the resultant current flow in the row line of the selected row of devices.

Abstract: An analog memory apparatus for storing and retrieving a sequence of samples of an analog signal is described. The apparatus includes a plurality of storage devices each storing each of the samples of the sequence with appropriate sign in accordance with a predetermined code. The samples stored in each device represent a respective algebraic sum of the samples of the sequence. To retrieve the samples of the analog signal the different algebraic sums of samples stored in the devices are algebraically summed in accordance with the predetermined code.

Abstract: Relates to an imaging array of charge storage devices each including a pair of closely coupled conductor-insulator-semiconductor cells, one a row line connected cell and the other a column line connected cell. By transferring signal charge in a row of devices simultaneously between the cells of each device and reading out the resultant signal on the row line common to the devices, a spatial transform of an image is directly read from the array.

Abstract: An array of charge storage devices each including a pair of closely coupled conductor-insulator-semiconductor cells, one a row line connected cell and the other a column line connected cell, is provided on a common semiconductor substrate. Read out of the charges stored in a row of devices is accomplished by obtaining the difference of pairs of signals, one sensed on the row line connecting the selected row of devices and the other of the signals sensed on the row line connecting an adjacent row of devices emptied of stored charge.
