Important Considerations on the Use of an Integrating Focal Plane Array Camera inan Optical Recognition System

摘要

With the development of CCD and CID technologies, many CCD and CID cameras withdifferent features and performance characteristics are available. This paper compares two cameras used as output transducers in a time-sequenced templet matching optical correlation system. CCD and CID cameras are used at the output of the optical correlator to integrate several high frame-rate time-sequenced output correlation responses derived from binary phase-only, filters (BPOFs). After integrating the responses, the camera presents the integrated correlation data to a microcomputer for statistical analysis in an attempt to detect the presence of targets in a changing binary input scene. This paper presents an evaluation of the cameras including a discussion of the advantages and disadvantages of camera features such as an image intensifier, an automatic gain control (AGC), and an on-board analog to digital (A/D) converter.
