Abstract:

Optimization of dichromated gelatin (DCG) film coatings for holographic recording is presented. The Taguchi optimization method is applied to DCG film coatings to obtain high uniformity. Two-level factorial design is used to optimize the emulsion curing conditions for high diffraction efficiency. Film thicknesses ranging from 6.0 to 23.4 mum are obtained with uniformities between 4.0 and 8.0%. Peak diffraction efficiencies between 87.0 and 96.9% are obtained using the optimized curing conditions. A possible holographic formation mechanism is introduced and experimental results for shrinkage an

Hybridizing, in general, is the approach of combining multiple technologies, materials, or designs such to mitigate the drawbacks and enhance the benefits. The result of this combination can be referred to as a hybrid. The projects described in this work concern a number of these hybrids. The collection of projects are limited to optical applications, but are otherwise enormously different. There is perhaps no better way to illustrate this breadth than their characteristic length-scale. That is, the general size of the elements being hybridized.

This thesis studies the TBC effect during the formation of a holographic grating in polymer-dispersed liquid crystal (PDLC) films pumped by two coherent Ar+-laser beams. This TBC is due to a non-stationary grating effect instead of the general photorefractive effect. Detailed discussion of the experimental results based on the TBC theory are made. The thesis emphasizes the studies of the dynamic coupling strength (gd ) during the formation of the grating , and of the r
