摘要： Four radiant energy detectors are arranged in a common plane in a substantially square configuration with each detector occupying a separate quadrant. Infra-red energy received from a target is focused onto the detectors by means of a lens, there being a chopper positioned between the lens and the detectors to chop the radiant energy in a periodic fashion. The outputs of diagonally opposite pairs of detectors are each directly fed to a separate differencing amplifier, where difference signals are generated. These difference signals are then added together and subtracted from each other in separate circuits in a predetermined manner to produce a first signal representing the departure in azimuth of the target from a reference axis running through the center of the detector array, and a second signal representing the departure in elevation of the target from this same axis. The azimuth and elevation signals are separately phase detected in phase detectors which are referenced to the chopper drive signal, the outputs of the phase detectors being filtered in low pass filters to produce DC signals representing the departure in azimuth and elevation of the target from the reference axis. These signals can be fed to an indicator or employed to drive a servo system which slews the support structure for the detectors so as to lock the detectors onto the target.

摘要： A single channel transmission and recording system for a scanner having a multi-channel array of dectors having a single delta modulator in the transmission unit and a single delta demodulator in the receiving unit. A plurality of analog signals, such as video signals sensed by infrared detectors, are each fed to an associated channel having an associated switch circuit. A suitable switch logic generator samples the switches in successive ascending order and subsequently in successive descending order. The sampled analog signals of each channel are fed to a signal delta modulator which converts them to a serial train of digital signals. A synchronizing code generator generates a synchronizing code word which is transmitted with the serial train of digital signals to a receiving station where the serial train of digital signals is reconverted to an analog signal similar to the sampled analog signals for display on a suitable device such as a cathode ray tube. A decoder decodes the synchronizing code word to initiate the frames of scan of the cathode ray tube and a suitable counter responsive to the decoder controls the sweep of the frames of scan in accordance with the sampling of each of the channels in successive ascending order and subsequently in successive descending order.

摘要： A radiant energy detection system includes a first and second pairs of radiation detectors, the detectors of each pair facing in opposite directions to each other, the first and second pairs being positioned in a mutually orthogonal relationship. The detectors may be joined together in a cube structure which is fixedly mounted on a support. A chopper mechanism is mounted over the detectors; this chopper mechanism being supported on a motor shaft for rotatable drive thereby around the detector assembly. The signals arriving at the detectors from a radiant energy source are chopped by the chopper to produce a periodically varying output signal from each of the detectors. the outputs from each detector pair are fed to a separate differencing amplifier which generates a signal in accordance with the difference therebetween; the outputs of the amplifiers being phase demodulated to provide signals having peak amplitudes representing the cosine and the sine respectively of the angle of the radiant energy source (target) from the detector assembly. The signal in accordance with the sine of the angle, and the signal in accordance with the cosine of the angle, are fed to an analog processor which generates output signals in accordance with the azimuth angle of the target, the angular quadrant in which it lies, and a signal which appears at the time maximum energy is being received by the detectors.
