Abstract:
An imaging system comprising:a two dimensional array of sensors arranged in a plurality of groups for receiving electromagnetic radiation, said sensors in said array providing a plurality of sensor signals;a signal processing circuit for receiving the sensor signals and for providing processed sensor signals;a plurality of multiplexer means, each multiplexer means for multiplexing processed sensor signals for sensors in a corresponding group to provide a plurality of multiplexed sensor signals; anda plurality of oscillator means, each oscillator means being responsive to a corresponding multiplexer, said oscillator means for receiving said multiplexed sensor signals to provide a plurality of oscillator output signals that are frequency modulated:a communication link including means for summing together signals outputted by said oscillators into a composite signal and an image processor coupled to said communication link, said communication link including means for separating data of the respective sensors from the composite signal for presentation to the image processor; andmeans coupled to said separating means for storing an image of a subject viewed by said array of sensors;wherein each of the oscillators is operative in a predetermined frequency band which serves to identify a column of said array, a modulation of the frequency of an oscillator associated with said band providing data of radiation intensity from the subject received at a sensor.
