Liquid Crystal Polarization Grating (LCPG) Technology
Non-mechanically reconfigurable optics with vastly superior size, weight, and power requirements compared to their mechanical counterparts
LCPGs for Non-Mechanical 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.
BNS has pioneered the use of LCPGs in non-mechanical beam steering and is the sole owner of the patent on this approach (US 8,982,313 B2) as well as other related patents.
Liquid crystal polarization gratings enable steering and focusing of light with unparalleled performance and ease-of-integration.
