Adaptive Holography in Liquid Crystal Light-Valves
By performing two-wave mixing experiments in a liquid crystal light-valve, optical beam amplification is obtained as a strongly resonant process to which a narrow frequency bandwidth is associated. This property is exploited to realize adaptive holographic interferometric systems able to efficiently detect displacements as small as fraction of picometers. Pressure radiation induced deformations...
متن کاملLiquid crystal light valves for slow light and applications
The large dispersive properties of wave mixing in liquid crystal light-valves allow obtaining fast and slow light with tunable group velocities. A slow light interferometer is shown by using this interaction.
متن کاملAdaptive Holography Interferometry in Liquid Crystal Light-valves
By performing two-beam coupling experiments in a liquid crystal light-valve, optical beam amplification is obtained as a strongly resonant process to which a narrow frequency bandwidth is associated. By exploiting this property, we realize an adaptive holographic interferometric system that is able to efficiently sensing displacements as small as fraction of picometers. The adaptive interferome...
متن کاملContrast properties of reflective liquid crystal light valves in projection displays
Projectors that use reflective light valves must employ beam splitters or analogous components to separate bright-state light from dark-state light, since both states must propagate in the space above the light valve. Polarization ray tracing shows that such beam splitters will not usually achieve high rejection of dark-state light when the beam has the typical angular divergence of about &IO"....
