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…
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…
