The invention relates to a preprocessing circuit for at least one hologram computation circuit that comprises an input interface device for receiving data of a scene to be displayed, a processing device for defined processing of the received data and for converting the data into a system-independent format with incorporation of specific parameters required for displaying the scene, and an output interface device for outputting and transmitting the converted data to at least one hologram computation circuit. An apparatus for computing a hologram for displaying a scene by means of a holographic display apparatus is also disclosed. The apparatus comprises at least one spatial light modulation device and a preprocessing circuit as described, and at least one hologram computation circuit for computing a hologram and for encoding the hologram for the at least one spatial light modulation device.
A preprocessing circuit for at least one hologram computation circuit, comprising:
A pipeline for real-time computation of holograms, which comprises a preprocessing circuit for preprocessing data of a scene and for directly activating components of at least one spatial light modulation device and at least one hologram computation circuit for computing holograms, where the preprocessing circuit and the at least one hologram computation circuit are each implemented on the basis of a field-programmable gate array (FPGA) and/or an application-specific integrated circuit (ASIC).
A method for computing a hologram for displaying a scene by means of a holographic display apparatus, which comprises at least one spatial light modulation device, where the computation of the hologram is carried out by means of a preprocessing circuit and at least one hologram computation circuit.
