Method for encoding computer-generated holograms using a correction function

A method for encoding computer-generated holograms into pixelated light modulators, each light modulator having an encoding surface that includes a pixel matrix whose pixels have a certain pixel shape and pixel transparency, comprising the steps of:

• creating an encoding region by extending a pyramidal body with a virtual observer window localized in a Fourier plane of the light modulator as a defined visibility region and with an object point of an object as a peak beyond the object point and projecting onto the encoding surface, and holographically encoding the object point as a sub-hologram,
• multiplying each individual sub-hologram with a correction function, wherein the correction function is a virtual-observer-window-specific reciprocal of the transform of the pixel shape and pixel transparency and is projected into a hologram plane,
• adding the corrected sub-holograms to form an entire hologram,
• encoding the entire hologram into the encoding surface of the light modulator as a computer-generated hologram composed of said sub-holograms, each representing one object point of an object which is to be reconstructed by the hologram.
