Autoencoder-based holographic image restoration
Tomoyoshi Shimobaba, Yutaka Endo, Ryuji Hirayama +8
We propose a holographic image restoration method using an autoencoder, which is an artificial neural network. Because holographic reconstructed images are often contaminated by di…
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 (=…
Handheld and low-cost digital holographic microscopy
Atsushi Shiraki, Yusuke Taniguchi, Tomoyoshi Shimobaba +2
This study developed handheld and low-cost digital holographic microscopy (DHM) by adopting an in-line type hologram, a webcam, a high power RGB light emitting diode (LED), and a p…
Arbitrary shape surface Fresnel diffraction
Tomoyoshi Shimobaba, Nobuyuki Masuda, Tomoyoshi Ito
Fresnel diffraction calculation on an arbitrary shape surface is proposed. This method is capable of calculating Fresnel diffraction from a source surface with an arbitrary shape t…
Computational wave optics library for C++: CWO++ library
Tomoyoshi Shimobaba, Jian Tong Weng, Takahiro Sakurai +6
Diffraction calculations, such as the angular spectrum method, and Fresnel diffractions, are used for calculating scalar light propagation. The calculations are used in wide-rangin…
Fast calculation of computer-generated-hologram on AMD HD5000 series GPU and OpenCL
Tomoyoshi Shimobaba, Tomoyoshi Ito, Nobuyuki Masuda +2
In this paper, we report fast calculation of a computer-generated-hologram using a new architecture of the HD5000 series GPU (RV870) made by AMD and its new software development en…
