Wedge-ring shaped detector synthesized with computer-generated hologram and its application in pattern recognition
The CGH/WRD system (computer generated hologram/wedge-ring shaped detector) were synthesized with CGH and CCD devices. It allows separation of the detector shape function from the detection function. The use of OGH makes it considerable flexibility in the detetion process. The design considerations are presented in detail with some experimental results on pattern recognition.
