The use of LCPGs in nonmechanical beam steering is a novel technique, and Meadowlark has the patent on this approach (US 8,982,313 B2).
Along with our customers, we have demonstrated this technology in a range of cutting-edge applications, from lidar to optical communications:
LCPGs for Nonmechanical Beam Steering and Switchable Optics
Liquid crystal polarization gratings (LCPGs) are diffractive elements that provide near-100% diffraction for circularly polarized light. When layered with thin polarization-controlling liquid crystal elements, LCPGs provide a means of non-mechanically reconfiguring light into different states, such as for beam steering or focusing.
