摘要： A process for controlling layer spacing in mixtures of smectic liquid crystal compounds comprises the step of combining a liquid crystal composition having a net negative thermal layer expansion in at least one tilted (or latent tilted) smectic mesophase and a liquid crystal composition having a net positive thermal layer expansion in at least one tilted (or latent tilted) smectic mesophase, each of the compositions comprising at least one smectic or latent smectic liquid crystal compound. The process enables control of layer spacing in the tilted smectic mesophase(s) and thereby control or suppression of chevron layer geometry.

摘要： A method of making an optical film includes the steps of making a substrate having a first major surface and a second major surface opposite the first surface and forming a plurality of curved sided cone structures on the first surface. Each of the curved sided cone structures include a base located on the first surface, a vertex, and a curved side formed from an arc extending between the base and the vertex. The optical gain and viewing angle for the film can be controlled by adjusting angles representing a shape of each curved sided cone structure at its vertex and base.

摘要： A method for the encryption and decryption of digital images based on cyclotomic polynomials and radiometric expressions comprising the steps of generating an encrypting transform, partitioning the digital images into data blocks, along with encrypting, transmitting, and decrypting the data blocks. Three common radiometric expressions are fundamental metamers, black metamers, and radiometric functions. In one embodiment, the mathematical equation that represents the encrypting transform is a cyclotomic polynomial. In another embodiment, a cyclotomic polynomial is used to calculate the coefficients of the mathematical equation that represents the encrypting transform. In other embodiments, the encrypting transform is generated with a radiometric expression, and the encrypted data blocks are calculated with a radiometric expression.
