Holography

, 2016
International audienceHolography, invented by Denis Gabor in 1948, allows the recording and reconstruction of a wavefront amplitude and phase. The development of optical holography started, in 1960, with the laser. The holographic principles and the most

Conversion of 2D picture to color 3D holography using end-to-end convolutional neural network

PhotoniX
In the field of holographic 3D display, generating a three-dimensional (3D) computer-generated hologram (CGH) from a single two-dimensional (2D) image has been a significant challenge due to the high-dimensionality of the problem.

Computer-Generated Holography : State of the Art

, 2014
This paper reviews Computer Generated Holography techniques. Using these methods, it is possible to acquire holograms of synthetic or existing scenes without physical interference between light waves. Most limitations characterizing conventional holography, namely the need for a powerful, highly coherent laser and extreme stability of the optical ...

Role of perceptually guided image quality metrics in computer-generated holography [PDF]

Computer-Generated Holography (CGH) algorithms relies on pixel-wise evaluation metrics for calculating holograms. Our work addresses a gap in the literature by evaluating various combinations of conventional pixel-wise metrics such as L2-norm and ...

Optical HAAR Wavelet Transforms using Computer Generated Holography

, 1992
This research introduces an optical implementation of the continuous wavelet transform to filter images. The wavelet transform is modeled as a correlation process and is implemented with a Vander Lugt correlator.
