Amp-Holo-Net enables speckle-free and high-quality coaxial amplitude-only holographic display Open
At present, amplitude-only holograms (AOH) are widely applied because of the high response speed and small pitch of amplitude spatial light modulators. However, AOHs are generally generated by traditional diffraction theories, and there ar…

Depth of field expansion method for integral imaging based on diffractive optical element and CNN Open
In lens-based display systems, lens aberrations and depth of field (DoF) limitation often lead to blurring and distortion of reconstructed images; Meanwhile, expanding the display DoF will face a trade-off between horizontal resolution and…

Convolutional symmetric compressed look-up-table method for 360° dynamic color 3D holographic display Open
In this paper, we propose a convolutional symmetric compressed look-up-table (CSC-LUT) method to accelerate computer-generated hologram (CGH) computation based on the Fresnel diffraction theory and LUT. The proposed method can achieve one-…

Holographic display using layered computer-generated volume hologram Open
The spatial frequency of the reconstructed image of planar computer-generated hologram(CGH) is limited by the sampling interval and the lack of thickness. To break through this limitation of planar CGH, we propose a new computer-generated …

Superpixel-based sub-hologram method for real-time color three-dimensional holographic display with large size Open
One of the biggest challenges for large size three-dimensional (3D) holographic display based on the computer-generated hologram (CGH) is the trade-off between computation time and reconstruction quality, which has limited real-time synthe…
