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
