Method and apparatus for dynamically variable electrical control of light beam reflective liquid crystal devices

[0056] In contrast to the prior art solutions discussed above that operate only in the transmissive mode, a reflective mode electrically controllable device is described according to the proposed solution, which aims to reduce the loss of light flux and reduce the variable optical reflection spatially continuous ( non-pixelated) devices that can be electrically controlled using electric fields and layers of controllable materials, such as liquid crystals or composite polymer cells. Such devices can be used for controllable reflection to provide beam steering, beam dispersion, steering, scattering, etc.

[0057] According to a first embodiment of the proposed solution, various combinations of substrates with different electrode configurations, LC materials and LC ground-state alignment can be used for the incident and rear substrates. According to the proposed solution, in the XY plane using such as Figure 4 Multiple beam steering elements are shown to build and provide large opt
