Abstract

Liquid crystal phase modulators or retarders have the potential to induce controlled, repeatable, dynamic aberrations into optical systems at low cost, low complexity, and high flexibility. We discuss the performance of a transmissive nematic device with 69 phase delay cells in a hexagonal pattern developed for the Phillips Laboratory by Meadowlark Optics. The emphasis on this research is the production and measurement of time varying phase distortions.
