Briefly, according to one aspect of the invention, liquid crystal material having a smectic phase is encapsulated; and according to further aspects there are provided methods for encapsulating liquid crystal material having a smectic phase and for making a liquid crystal device using such encapsulated liquid crystal material.

Encapsulated liquid crystal having a smectic phase

An apparatus for responding to incident electromagnetic radiation includes a first medium having a surface and through which incident electromagnetic radiation may be transmitted, a second such medium having a surface, the surfaces being generally parallel, and smectic liquid crystal between said surfaces and aligned generally in parallel in layers that extend generally parallel to each other and perpendicularly to such surfaces (bookshelf alignment), the liquid crystal material being operative to undergo self-focusing in response to a characteristic of incident electromagnetic radiation exceeding a value and being cooperative with at least one of such media thereby automatically to limit the energy or energy density of electromagnetic radiation exiting the apparatus.

High speed optical protection using smectic liquid crystal

A liquid crystal apparatus including a latex containment medium, a liquid crystal material dispersed in plural volumes in the medium, and a barrier means forming a wall in plural volumes in said medium so as to preserve the integrity of the volumes of the liquid crystal material.
