Liquid Crystal Polarization Gratings
Meadowlark Liquid Crystal Polarization Gratings
Non-mechanically reconfigurable optics with vastly superior size, weight, and power requirements compared to their mechanical counterparts
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).
Industries Using LCPG Technology
Along with our customers, we have demonstrated this technology in a range of cutting-edge applications, from lidar to optical communications:
- Aerospace: Inertialess optical beam steering with dramatic reductions of size, weight, and power
- Automotive: Wide-angle steering of flash and coherent lidar for ADAS and autonomous vehicles
- Manufacturing + Automation: Increase range and resolution of conventional Time-of-Flight cameras without sacrificing field of view
- Telecommunication: Nonmechanical coarse pointing, acquisition, and tracking, as well as nonmechanical divergence control
- Wind Power Generation: Compact nonmechanical pointing of coherent Doppler lidar wind sensing
Applications
What ARE LIQUID CRYSTAL POLARIZATION GRATINGS?
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.
