Ultrasonic Coating and Holographic Exposure Technology. Phase 1
Abstract
This report describes research efforts by Revision Military Technologies, LLC. in the development of an ultrasonic coating and holographic exposure technology to apply diffraction gratings onto planar substrates. An ultrasonic coater is used to apply a thin film of a photosensitive azobenzene layer to a hard coated polycarbonate substrate, which is then irradiated with a 442 nm wavelength laser to expose a diffraction grating pattern. Then, the substrate is over-coated with a liquid crystal monomer to develop the diffraction grating. Crystallization and dewetting indicated a chemical incompatibility between the azobenzene and liquid crystal, and improvements in chemistry were suggested in advance of Phase II.
