Beam steering with spatial light modulators: Quantisation effects
... A. Beam steering with spatial light modulators Phase-only spatial light modulators are used in beam steering. In order to do that, holograms are encoded to the SLM, producing different beam’s directions. Holograms are pixel images defined by grey levels. The electronics of the SLM converts the value ...
