Extended Depth-of-Field Lensless Imaging using an Optimized Radial Mask
Jose Reinaldo Cunha Santos A V Silva Neto, Tomoya Nakamura, Yasushi Makihara +1
The freedom of design of coded masks used by mask-based lensless cameras is an advantage these systems have when compared to lens-based ones. We leverage this freedom of design to…
Hom-Poisson-Nijenhuis structures on Hom-Lie algebroids and Hom-Dirac structures on Hom-Courant algebroids
Tomoya Nakamura
In this paper, we develop the theory of Hom-Lie algebroids, Hom-Lie bialgebroids and Hom-Courant algebroids introduced by Cai, Liu and Sheng. Specifically, we introduce the notions…
Pseudo-Poisson Nijenhuis manifolds
Tomoya Nakamura
We introduce the notion of pseudo-Poisson Nijenhuis manifolds. These manifolds are generalizations of Poisson Nijenhuis manifolds by Magri and Morosi \cite{MM}. We show that any ps…
The deformations of symplectic structures by moment maps
Tomoya Nakamura
We study deformations of symplectic structures on a smooth manifold via the quasi-Poisson theory. By a fact, we can deform a given symplectic structure to a new symplectic…
Design of a Nanometer Beam Size Monitor for ATF2
Taikan Suehara, Masahiro Oroku, Takashi Yamanaka +8
We developed an electron beam size monitor for extremely small beam sizes. It uses a laser interference fringe for a scattering target with the electron beam. Our target performanc…
High Resolution Cavity BPM for ILC Final Focal System (IP-BPM)
Tomoya Nakamura, Yosuke Honda, Yoichi Inoue +4
IP-BPM (Interaction Point Beam Position Monitor) is an ultra high resolution cavity BPM to be used at ATF2, a test facility for ILC final focus system. Control of beam position in…
