Beam angle-locked loop in laser interferometry
Daikang Wei, Christoph Bode, Vitali Müller +2
Maintaining precise beam coalignment is essential in laser interferometry, particularly for interspacecraft missions where angular misalignments introduce tilt-to-length coupling n…

Nested active pointing control for interspacecraft laser interferometry
Daikang Wei, Christoph Bode, Yihao Yan +3
Precise pointing control is critical for interspacecraft laser interferometry, as angular misalignment introduces measurement noise and can even lead to laser link loss. We present…

Experimental Demonstration of an On-Axis Laser Ranging Interferometer for Future Gravity Missions
Daikang Wei, Christoph Bode, Kohei Yamamoto +6
We experimentally demonstrate a novel interferometric architecture for next-generation gravity missions, featuring a laser ranging interferometer (LRI) that enables monoaxial trans…
