Provided are holographic display systems and methods for generating a hologram by compensating for aberrations of a holographic display device. The holographic display system may include a holographic display device and a hologram generating device. The hologram generating device may generate a hologram by propagating hologram segments, using kernels generated by modeling each aberration corresponding to each of hologram plane segments to compensate for aberrations.

Holographic display system and method for generating hologram by compensating for aberration of holographic display device

A retinal projection display device is provided. The retinal projection display device includes a light source configured to emit light, a spatial light modulator configured to generate diffracted light by diffracting the emitted light, a holographic optical element configured to reflect the diffracted light by duplicating the diffracted light into a plurality of complex wavefronts, and a field lens configured to focus the plurality of complex wavefronts to a plurality of respective focal points in an eye-box, wherein the plurality of complex wavefronts overlap each other.

Retinal projection display device and phase profile optimization method thereof

Provided is a method of generating a hologram, the method including generating a kernel and a neural network configured to model an aberration of a holographic display device, obtaining second image data output from the neural network to which first image data obtained by propagating a first hologram based on the kernel is input, updating the kernel and the neural network based on comparing the second image data and predetermined image data, and generating a second hologram based on the kernel and the neural network.
