Quantized neural network for complex hologram generation
Yutaka Endo, Minoru Oikawa, Timothy D. Wilkinson +2
Computer-generated holography (CGH) is a promising technology for augmented reality displays, such as head-mounted or head-up displays. However, its high computational demand makes…
Improvement of the image quality of random phase--free holography using an iterative method
Tomoyoshi Shimobaba, Takashi Kakue, Yutaka Endo +8
Our proposed method of random phase-free holography using virtual convergence light can obtain large reconstructed images exceeding the size of the hologram, without the assistance…
Random phase-free kinoform for large objects
Tomoyoshi Shimobaba, Takashi Kakue, Yutaka Endo +7
We propose a random phase-free kinoform for large objects. When not using the random phase in kinoform calculation, the reconstructed images from the kinoform are heavy degraded, l…
Fast computation of computer-generated hologram using Xeon Phi coprocessor
Koki Murano, Tomoyoshi Shimobaba, Atsushi Sugiyama +4
We report fast computation of computer-generated holograms (CGHs) using Xeon Phi coprocessors, which have massively x86-based processors on one chip, recently released by Intel. CG…
Non-uniform sampled scalar diffraction calculation using non-uniform fast Fourier transform
Tomoyoshi Shimobaba, Takashi Kakue, Minoru Oikawa +4
Scalar diffraction calculations such as the angular spectrum method (ASM) and Fresnel diffraction, are widely used in the research fields of optics, X-rays, electron beams, and ult…
Gigapixel inline digital holographic microscopy using a consumer scanner
Tomoyoshi Shimobaba, Hiroya Yamanashi, Takashi Kakue +6
We demonstrate a gigapixel inline digital holographic microscopy using a consumer scanner. The consumer scanner can maximally scan an A4 size image (297mm x 210mm) with 4800 dpi (=…
Aliasing-reduced Fresnel diffraction with scale and shift operations
Tomoyoshi Shimobaba, Takashi Kakue, Naohisa Okada +3
Numerical simulation of Fresnel diffraction with fast Fourier transform (FFT) is widely used in optics, especially computer holography. Fresnel diffraction with FFT cannot set diff…
