Optical Truss Interferometer for the LISA Telescope
Kylan Jersey, Ian Harley-Trochimczyk, Yanqi Zhang +1
The LISA telescopes must exhibit an optical path length stability of in the mHz observation band to meet mission requirements. The optical…
Optomechanical cooling and inertial sensing at low frequencies
Yanqi Zhang, Adam Hines, Dalziel Wilson +1
An inertial sensor design is proposed in this paper to achieve high sensitivity and large dynamic range in the sub-Hz frequency regime. High acceleration sensitivity is obtained by…
A characterization method for low-frequency environmental noise in LIGO
Guillermo Valdes, Adam Hines, Andrea Nelson +2
We present a method to characterize the noise in ground-based gravitational-wave observatories such as the Laser Gravitational-Wave Observatory (LIGO). This method uses linear regr…
Investigation and mitigation of noise contributions in a compact heterodyne interferometer
Yanqi Zhang, Adam Hines, Guillermo Valdes +1
We present a noise estimation and subtraction algorithm capable of increasing the sensitivity of heterodyne laser interferometers by one order of magnitude. The heterodyne interfer…
Quasi-monolithic heterodyne laser interferometer for inertial sensing
Yanqi Zhang, Felipe Guzman
We present a compact heterodyne laser interferometer developed for high-sensitivity displacement sensing applications. This interferometer consists of customized prisms and wavepla…
Fiber-based two-wavelength heterodyne laser interferometer
Yanqi Zhang, Felipe Guzman
Displacement measuring interferometry is a crucial component in metrology applications. In this paper, we propose a fiber-based two-wavelength heterodyne interferometer as a compac…
Optomechanical accelerometers for geodesy
Adam Hines, Andrea Nelson, Yanqi Zhang +4
We present a novel optomechanical inertial sensor for low frequency applications and corresponding acceleration measurements. This sensor has a resonant frequency of 4.7Hz, a mecha…
A compact high-precision periodic-error-free heterodyne interferometer
Ki-Nam Joo, Erin Clark, Yanqi Zhang +2
We present the design, bench-top setup, and experimental results of a compact heterodyne interferometer that achieves picometer-level displacement sensitivities in air over frequen…
