Evaluation of a Ferroelectric Liquid Crystal Spatial Light Modulator

Abstract

Key performance characteristics of an optically-addressed ferroelectric liquid crystal spatial light modulator have been measured and compare favorably with other commercially available SLMs. Several characteristics which are important for optical pattern recognition, including imaging resolution, visibility, and response time, are discussed in this communication. The maximum resolution was measured to be 40 lp/mm with an imaging response time of 60 Hz. This differs substantially from previously published results. This is primarily due to operating the device so as to maintain good resolution with moderate illumination. Furthermore, experimental results to determine the modulated response of the read beam as a function of the write light intensity will also be presented. (Author)
