Synthesizing optical field is one of the most fascinating studies in optics. There are many applications for this technique like holographic display, optical beaming, structured illumination, optical tweezers, and so on. In this technique, one of interesting issues is to increase the bandwidth product of synthesized field. I constructed a spatial light modulator with twisted nematic liquid crystal by myself and I demonstrated a wide-angle holographic stereogram overcoming the limitation of bandwidth product that a single SLM has.
