Laser beam steering is an important feature of almost all military laser systems. Beam steering is in this context defined using a broad description including; beam deflection, pointing, scanning, stabilization etc. The traditional method to perform laser beam steering is to utilize a mirror. However, mirrors suffer from several drawbacks such as e.g. movable parts, mechanical complexity, power requirements and high costs. Recent developments in the field of liquid crystal (LC) technology have shown that laser beam steering can be accomplished with devices based on LC materials. By using the LC device as a spatial light modulator (SLM) to modulate the phase of the laser beam wavefront beam steering can be performed. The purpose of this study was to review the field of laser beam steering, identify important applications for LC beam steering, study technical requirements, analyze the LC beam steering concept and specify a LC beam steering component.
