A frame integrator for integrating each of the outputs of an array of radiation detectors whose output is obtained by the charge-injection-device technique. An array of analog integrators is connected using row and column interconnection techniques with an array of radiation detectors. The output from each radiation detector is sampled periodically and the detector returned to its unexposed condition to avoid saturation of the detector. The analog integrator associated with each detector integrates the sampled output of the detector to increase the effective sensitivity of the detector and to reduce the noise in the output. Each analog integrator consists of a precharged capacitor which is discharged through a field effect transistor in an amount proportional to the output of the associated radiation detector.
