Abstract

A new algorithm for producing DC balanced sets of holograms designed to be used on ferroelectric liquid crystal displays is presented in this article. The algorithm minimises Fourier plane intensity fluctuations while guarantees equal per-pixel phase states by exploiting phase shifting that are not be detected by photodetectors. It improves on the scrolling method employed for single beam steering by allowing complex beam patterns, such as multiple beams or beams with defocusing, to be DC balanced effectively. A proof of concept point-to-multipoint optical transmission system is presented, demonstrating the feasibility of obtaining good optical transmissions for complex beam shapes.
