We have invented an efficient phase-only light shaping modality that can simultaneously control the distribution of multiple beams and shaping of these beams individually in a volume. It is coined Holo-GPC and extends the capabilities of both Generalized Phase Contrast (GPC) and Holography. Holo-GPC can be considered as a hybrid combination of holography that can create extended 2D or 3D beam distributions and GPC that forms noise-free sculpting of the individual beams.
