Jiggled interferometer: Ground-based gravitational wave detector using rapidly-repeated free-falling test masses
Shoki Iwaguchi, Bin Wu, Kurumi Umemura +10
We propose the Jiggled Interferometer (JIGI), a novel ground-based gravitational wave detector employing low-frequency noise mitigation similar to that of space-based detectors. Us…
Initial acquisition requirements for optical cavities in the space gravitational wave antennae DECIGO and B-DECIGO
Yuta Michimura, Koji Nagano, Kentaro Komori +8
DECIGO (DECi-hertz Interferometer Gravitational Wave Observatory) is a space-based gravitational wave antenna concept targeting the 0.1-10 Hz band. It consists of three spacecraft…
Proof-of-principle demonstration of a Polarization-Circulation Speed Meter
Yohei Nishino, Tomotada Akutsu, Yoichi Aso +3
We present the first experimental implementation of a polarization-circulation speed meter. In our experiment, the interferometer was reduced to a single-cavity configuration with…
SILVIA: Ultra-precision formation flying demonstration for space-based interferometry
Takahiro Ito, Kiwamu Izumi, Isao Kawano +26
We propose SILVIA (Space Interferometer Laboratory Voyaging towards Innovative Applications), a mission concept designed to demonstrate ultra-precision formation flying between thr…
Modeling of optical scattering from topographic surface measurements of high-quality mirrors
Tomotada Akutsu, Hiroaki Yamamoto
In this paper, we revisit computational methods to obtain an angular profile of optical scattering from a smooth surface, given a two-dimensional map of topographic height errors o…
