Abstract

Thermoplastic, as a relief image recording material, has several advantageous characteristics. All processing is dry, development is almost instantaneous and in situ, and the recorded image can be erased and reused. Theoretical studies have shown that the amount of relief image formed in a thermoplastic is a function of the thermoplastic thickness and frequency of input exposure. This thesis shows that this relationship is valid under a number of physical restraints. Results indicate that there is a thickness to input-signal-modulation interaction within the thermoplastic. With variable frequency sinusoids as the input, the physical structure of the relief fringes formed is optimized when the input modulation is decreased, but there is also an 88% decrease in diffraction efficiency. Therefore higher spatial frequencies can be obtained for the thinner thermoplastics if a decrease in diffraction efficiency can be tolerated.
