Examples of CGH algorithm types (IMAGE)
Caption
a, Diagram of a point-cloud CGH algorithm, showing typical axis conventions. Every point of the ship model point cloud creates a point-spread function on the hologram plane (color code: hue corresponds to phase, brightness to amplitude). The superposition of all point-spread functions yields the final hologram. b, Diagram of layer-based CGH, showing how a 3D object is segmented into layers, where every scene element is assigned to its closest intermediate wavefront. Here, an exemplary point with its PSF influence region on the matching layer is shown. All layers are accumulated into a hologram using e.g., convolutional numerical propagation.
