<p>Disclosed is an optical system (312) and an imaging and display system using the optical system. The optical system has at least first (330) and second (332) optical elements aligned on a common axis (334). In one embodiment, each of the first and second optical elements can operate in an active state or in inactive state and comprise a photopolymer and liquid crystal combination (12). Each of the first and second optical elements is configured to transmit incident light substantially unaltered when each of the first and second optical elements operates in the inactive state. In the active state, however, each of the first and second optical elements does not transmit incident light substantially unaltered. Rather each of the first and second optical elements substantially alters light incident thereon when each of the first and second optical elements operates in the active state.</p> |
