摘要： 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.

摘要： In an array of charge injection device (CID) detectors, integer amplification is incorporated into each respective detector of the array. The amplifier for each CID detector in the array performs multiple nondestructive readouts. This provides a gain of N amplification of the signal charge in that detector wherein the signal charge is accurately replicated in a separate charge storage well defined by a magnitude capacitor coupled to the detector. Thus, at the end of the readout process, this separate well contains charge equal to N times the signal charge, N being the number of nondestructive readout cycles in the readout process.

摘要： Intensity of optical emission from a combustion flame within a gas turbine combustor is monitored through an optical window in the combustor wall by a primary detector. Because the window is susceptible to becoming coated with deposits during combustor operation, compensation for presence of a coating is achieved by directing illumination from an optical signal source, such as a silicon carbide light-emitting diode, into the window for internal reflection at an optical interface defined by the combustion side surface. A compensation detector, such as a silicon carbide photodiode, detects intensity of the internally reflected illumination as an indicator of the window coating thickness. The compensation detector is located at a non-combustion side of the window, along with a reference detector that responds to intensity of optical signal source illumination reflected from the non-combustion side surface of the window. An AC coupled differential synchronous detector circuit processes the compensation detector and reference detector output signals to compensate the primary detector output signals for the coating.

摘要： An array of charge storage devices each including a pair of closely coupled conductor-insulator-semiconductor capacitors or cells, one a row line connected cell and the other a column line connected cell, is provided on a common semiconductor substrate. The charge stored in a row of devices is read out by transferring charge from a column cell to a row cell and then back again to the column cell by reducing and then increasing the absolute value of the voltage on column cell of each of the devices of the row in sequence. The resultant change in voltage produced on the row line is sensed and an electrical signal is obtained representing the charge stored at each of the devices of the row. During the readout operation the voltage on each of the column cells is reduced to below threshold voltage of the cells to allow the fixed amount of charge trapped in the surface states of each of the column cells to recombine with majority carriers in the substrate thereby reducing the charge stored in each of the devices of the array by this fixed amount of charge.

摘要： A charge injection device image sensor, having increased sensitivity and dynamic range, uses a two dimensional array of cells having m rows each with n cells arranged in n columns. Peripheral electronics first reset all cells along each of the columns, then sequentially scan each column to generate a row voltage signal before advancing to the next sequential row and repetitively scanning across the cells until all array cells have been raster scanned. A voltage preamplifier is connected to each associated row to amplify the video signal only when the cells along that row are being scanned, and reduces the total capacitance of the row-selection electronics.

摘要： An output circuit for use with an array of high dynamic range analog sensor produces a digital output signal from the array prior to multiplexing, so as to avoid analog multiplexing noise. The analog signals are converted to digital form using a simple, parallel analog-to-digital conversion process at the outputs of low noise array amplifiers. By latching the converted digital output signals into shift registers, the analog multiplex function is obviated and the full dynamic range capability of the detector-amplifier combination is made available.

摘要： 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.
