Abstract

Two cameras used as output transducers in a time-sequenced templet-matching optical correction system are compared. One camera, a charge-injection device (CID) camera, is equipped with an image intensifier, automatic gain control (AGC), and a standard video output, while the second camera is a charge-coupled device (CCD) camera without an intensifier or AGC but with a computer interface custom-designed to use the camera's digital output. The cameras are used at the output of the optical correlator in order to integrate high frame-rate time-sequenced output correlation responses derived from binary phase-only filters. It is concluded that an image intensifier is the most important feature to have in a CCD or CID camera because the use of it results in a shorter integration time.
