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…
Calculation reduction method for color computer-generated hologram using color space conversion
Tomoyoshi Shimobaba, Takashi Kakue, Minoru Oikawa +5
We report a calculation reduction method for color computer-generated holograms (CGHs) using color space conversion. Color CGHs are generally calculated on RGB space. In this paper…
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…
