Journal ArticleDOI
Parallel two-step phase-shifting digital holography
Yasuhiro Awatsuji,Tatsuki Tahara,Atsushi Kaneko,Takamasa Koyama,Kenzo Nishio,Shogo Ura,Toshihiro Kubota,Osamu Matoba +7 more
TL;DR: A parallel two-step phase-shifting digital holography technique capable of instantaneous measurement of three-dimensional objects, with a view toward measurement of dynamically moving objects, based on phase- shifting interferometry is proposed.
Journal ArticleDOI
High-speed phase imaging by parallel phase-shifting digital holography
Takashi Kakue,Ryosuke Yonesaka,Tatsuki Tahara,Yasuhiro Awatsuji,Kenzo Nishio,Shogo Ura,Toshihiro Kubota,Osamu Matoba +7 more
TL;DR: This work demonstrated high-speed parallel phase-shifting digital holography and obtained images of the phase variation of air caused by a compressed gas flow sprayed from a nozzle and found the interesting phenomenon of periodic phase distributions.
Journal ArticleDOI
Digital holography and its multidimensional imaging applications: a review.
TL;DR: Digital holography can be used to perform multidimensional imaging of three-dimensional structure, dynamics, quantitative phase, multiple wavelengths, and polarization state of light and sensing of a holographic image of nonlinear light and a three- dimensional image of incoherent light.
Journal ArticleDOI
Parallel phase-shifting digital holographic microscopy
Tatsuki Tahara,Kenichi Ito,Takashi Kakue,Motofumi Fujii,Yuki Shimozato,Yasuhiro Awatsuji,Kenzo Nishio,Shogo Ura,Toshihiro Kubota,Osamu Matoba +9 more
TL;DR: The PPSDHM has the ability of three-dimensional motion measurement using space-division multiplexing technique and instantaneous information of both the 3-D structure and the phase distributions of specimens can be simultaneously acquired with a single-shot exposure.
Journal ArticleDOI
Experimental demonstration of parallel two-step phase-shifting digital holography.
Tatsuki Tahara,Kenichi Ito,Motofumi Fujii,Takashi Kakue,Yuki Shimozato,Yasuhiro Awatsuji,Kenzo Nishio,Shogo Ura,Toshihiro Kubota,Osamu Matoba +9 more
TL;DR: In the experiment, the unwanted images, the zero-order diffraction wave and the conjugate image, are removed from the reconstructed image of objects by the system, while the images superimpose on the image of Objects reconstructed by Fresnel transform alone.
