Journal ArticleDOI
Iterative algorithm of phase determination in digital holography for real-time recording of real objects
TL;DR: A numerical method to obtain complex amplitude distribution of a three-dimensional (3D) object from a digital hologram based on the criterion that the reconstructed 3D object is in focus and its conjugate reconstruction is out of focus.
Journal ArticleDOI
High Dynamic Range Digital Holography and Its Demonstration by Off-Axis Configuration
Ryosuke Yonesaka,Yonghee Lee,Peng Xia,Tatsuki Tahara,Yasuhiro Awatsuji,Kenzo Nishio,Osamu Matoba +6 more
TL;DR: In the numerical simulation and experiment, the quality of the reconstructed images by the proposed technique is higher than that by the conventional digital holography without HDR imaging.
Journal ArticleDOI
Numerical estimation of storage capacity in reflection-type holographic disk memory with three-dimensional speckle-shift multiplexing.
TL;DR: This work fabricates a simulator to evaluate reflection-type holographic data storage by calculating wave propagation, recording a hologram, and reconstruction by scalar diffraction, and calculates the properties of the resultant diffraction efficiency at the first null in the speckle-shift multiplexing.
Journal ArticleDOI
Structural Design of Nonlinear optical Chromophores for High-Performance Photorefractive Polymers
G.B. Jung,Kayoko Honda,Toshiki Mutai,Osamu Matoba,Satoshi Ashihara,Tsutomu Shimura,Koji Araki,Kazuo Kuroda +7 more
TL;DR: In this paper, the photorefractive response rate in a polymer composite of poly(N-vinylcarbazole)/2,4,7-trinitro-9-fluorenone, doped with 2,5-dimethyl-4-(4'-nitrophenylazo)anisole (DMNPAA) is improved by modifying the structure of DMNPAA.
Journal ArticleDOI
Image recovery from defocused 2D fluorescent images in multimodal digital holographic microscopy.
TL;DR: A method to recover the def focused images based on the phase compensation and backpropagation from the defocused plane to the focused plane using the distance information that is obtained from a 3D phase distribution is proposed.
