We use a liquid crystal spatial light modulator to construct a computed wave that would have emanated from a hypothetical object that we mathematically specify. The method uses optimal filter theory and realistic devices. We show laboratory results. The method applies to video holograms and small head-up displays. The method was inspired by work using binary reflective SLMs, and we adapted it to a continuously variable and highly coupled operating curve.
