Postprocessing of tilt-to-length noise with coefficient drifts in TianQin using a null time-delay interferometry channel
Zhizhao Wang, Shuju Yang, Kaihang Wu +5
Tilt-to-length (TTL) coupling is expected to be one of the major noise sources in the interferometric phase readouts in TianQin mission. Arising from the angular motion of spacecra…
Experiment demonstration of tilt-to-length coupling suppression by beam-alignment-mechanism
Peng Qiu, Xiang Lin, Yurong Liang +3
Tilt-to-length (TTL) noise, caused by angular jitter and misalignment, is a major noise source in the inter-satellite interferometer for gravitational wave detection. However, the…
Advanced pure tilt actuator for testing tilt-to-length coupling in space-based gravitational wave detection
Xiang Lin, Qi Xia, Peng Qiu +2
Tilt-to-length (TTL) coupling, caused by the jitter of test masses or satellites, is a significant noise source in space-based gravitational wave detection. Calibrating and suppres…
Quasi-monolithic Compact Interferometric Sensor Head Design with Laser Auto-alignment
Xiang Lin, Peng Qiu, Yurong Liang +3
Interferometers play a crucial role in high-precision displacement measurement such as gravitational-wave detection. Conventional interferometer designs require accurate laser alig…
