Six-degrees-of-freedom test mass readout via optical phase-locking heterodyne interferometry
Xin Xu, Jinsong Liu, Henglin Mu +2
Accurate position and posture measurements of the freely-falling test mass are crucial for the success of spaceborne gravitational wave detection missions. This paper presents a no…
Laboratory development of a heterodyne interferometric system for translation and tilt measurement of the proof mass in the space gravitational wave detection
Xin Xu, Yidong Tan
Laser heterodyne interferometry plays a key role in the proof mass's monitor and control by measuring its multiple degrees of freedom motions in the Space Gravitational Wave Detect…
Noncontact measurement method of linear and angular displacement based on dual-beam feedback interferometric system
Xin Xu, Zongren Dai, Yidong Tan
This study describes a unique optical approach for the noncontact measurement of linear and angular displacement. Compared to previous methods, the sensor system here based on the…
High sensitivity and full-circle optical rotary sensor for non-cooperatively tracing wrist tremor with nanoradian resolution
Xin Xu, Zongren Dai, Yifan Wang +2
An optical rotary sensor based on laser self-mixing interferometry is proposed, which enables noncontact and full-circle rotation measurement of non-cooperative targets with high r…
