Meadowlark Optics Liquid Crystal Polarization Gratings (LCPG) and Lenses (LCPL)
Description
Meadowlark Optics’ Liquid Crystal Polarization Gratings utilize spatially varying birefringence to create highly efficient polarization-sensitive gratings. Circularly polarized light can be directed into either the +1 or -1 order depending on the handedness of the incident light. By using a stack of N LCPGs and half-waveplate switches, it is possible to steer to 2ᴺ discrete angles in 1-D or 2-D arrays.
