Using Liquid Crystal Spatial Light Modulators for Closed Loop Tracking and Beam Steering with Phase Holography (Paperback) (ISBN-13: 9781288331499)

Optical Phased Array (OPA) technology offers advantages in the reduction of size, weight, and power of optical steering devices. Nematic liquid crystal (LC) spatial light modulators (SLMs) have been studied as a potential candidate for building non-mechanical OPAs. They can steer a laser beam and split the beam into multiple beams. This thesis builds upon the prior research showing each split beam can be individually controlled, including variation in intensity. A closed loop tracking scenario shows the flexibility of the SLM by tracking and stabilizing an incoming beam. Results show that applying a phase grating to the SLM has limitations with diffraction and fringing when the SLM is divided into sub-apertures during beam splitting, forcing trade-offs in performance.
