Liquid Crystal Polarization Grating Application Note

Meadowlark Optics Download the LCPG App Note Liquid Crystal Polarization Gratings (LCPGs)  This application note describes the use of Liquid Crystal Polarization Gratings (LCPGs) in aerospace, automotive, manufacturing & automation, telecommunications, and wind power generation industries. LCPGs are nonmechanically reconfigurable optics with vastly superior size, weight, and power requirements compared to their mechanical counterparts. Meadowlark […]

LCPG Principles

Download PDF Fundamentals Liquid crystal polarization gratings (PGs) are fascinating optical components that differ from traditional diffraction gratings, like ruled, Bragg, or holographic gratings. In particular, PGs exhibit polarization sensitivity, can have diffraction efficiency approaching 100%, and are much less sensitive to incident angle than, for example, Bragg or volume holographic gratings. To understand how
