Field: Optics (Instruments)
Classification: CPC G | IPC G

Claim 18:
19. The holographic display apparatus of claim 18, wherein the image processor is further configured to calculate the position and the inclined angle of the imaged planes by:
rotation-transforming a wavefront of one image plane into a plane parallel to the spatial light modulator;
propagating the rotation-transformed plane to a center of a first next plane;
rotation-transforming the wavefront such that the propagated plane is parallel to the first next plane;
replacing the rotation-transformed plane with the first next plane;
rotation-transforming a wavefront of the first next plane in parallel with the spatial light modulator to propagate to a second next plane, and repeating the rotation-transforming and propagating until a last plane is reached, and
generating hologram data by calculating the CGH by back-propagating the last plane to the spatial light modulator when reaching the last plane.
