Electron Beam Generated Holographic Optical Element Research.
Abstract
This report describes progress of the e-beam generated holographic optical element research program during 1981. We investigated partitioned computer generated holographic masks for optical matrix-vector multiplication. These masks are partitioned into separate areas for each channel, with each of these areas containing a linear grating to diffract light to its designated detector. A single lens completes the optical system. The space variant properties of the mask allow post-fabrication trimming for amplitude control. We have demonstrated the optical equivalent of a 1 x 10 matrix operation. In separate experiments, we have encoded matrices with numerical accuracies of 20 dB and a numerical range of 37 dB. These results were limited primarily by the stability of the input light source. (Author)
