Information about the physics and chemistry of liquid crystals is easy to come by, but information about applications is generally limited to technical papers or conference proceedings. Here scientists from industry and academia describe current and future applications such as three-dimensional holographic displays, projection displays, telecommunication devices, optical data processing devices, adaptive optics devices, and spatial light modulators. The chapters are intended to be accessible to non-specialists and also to provide useful information to specialists. Distributed in the US by AIDC.
