Range Emulator: A Compact Paraxial Optical System to Emulate Long-Distance Monochromatic Laser Propagation
Subaru Shibai, Kiwamu Izumi
Emulating long-distance light propagation on a laboratory scale is essential for the ground-based testing of intersatellite optical systems. To address this challenge, we propose a…
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…
Space-based cm/kg-scale Laser Interferometer for Quantum Gravity
Nobuyuki Matsumoto, Katsuta Sakai, Kosei Hatakeyama +5
The experimental verification of the quantum nature of gravity represents a milestone in quantum gravity research. Recently, interest has grown for testing it via gravitationally i…
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…
Demonstration of tilt sensing using a homodyne quadrature interferometric translational sensor
Koji Nagano, Karera Mori, Kiwamu Izumi
Future gravitational wave observation in space will demand improvement in the sensitivity of the local sensor for the drag-free control. This paper presents the proposal, design, a…
Cross-Correlated Force Measurement for Thermal Noise Reduction in Torsion Pendulum
Yusuke Okuma, Kiwamu Izumi, Kentaro Komori +1
The torsion pendulum is a prevailing instrument for measuring small forces acting on a solid body or those between solid bodies. While it offers powerful advantages, the measuremen…
