Thermoplastic Holographic Recording of Binary Patterns in PLZT Line Composer

It is possible to record holograms on a thermoplastic-photoconductor medium coated over a reflective substrate. Both analysis and experiment will be presented. The analysis shows that during recording only the interference term responsible for the formation of the primary image generates significant electrostatic fringes while other interference terms contribute insignificantly to electrostatic fringe formation. In the reflective readout mode, two reconstructed images are superimposed to give a three- to fourfold increase in the diffraction efficiency.

A 100-bit slitlike aperture array spatial light modulator has been developed using 8.8/65/35 PLZT for a high-bit-density 1-D hologram memory. The most desirable characteristics, such as distortion-free diffraction-limited Fourier transform patterns and good uniformity of displayed bit patterns over 100 bits, have been realized. The lowest SNR was 86, and rise time and fall time have been 30 microsec and 8 microsec, respectively, at 190-V halfwave voltage. One-dimensional holographic storage experiments have been successfully performed using this PLZT spatial light modulator.
