摘要太极计划需要通过激光捕获指向系统实现两颗卫星之间超长距离(3× 106 km)
的激光链路构建, 并且实现1 μrad 的捕获精度以及10 nrad/Hz (1 mHz~ 1 Hz) …

Optical phased arrays (OPAs) are devices that use the coherence of light to control the
interference pattern in the far field, which enables them to steer a laser beam with no moving …

The GRACE Follow-On satellite mission measures distance variations between its two
satellites in order to derive monthly gravity field maps, indicating mass variability on Earth on …

We propose a method to track signals from quadrant photodiodes (QPDs) in heterodyne
laser interferometers that employ digital phase-locked loops for phase readout. Instead of …

The measurement of the static and temporal variation of Earth's gravity field yields important
information on water storage, seasonal and sub-seasonal water cycles, their impact on …

Abstract Since 2002, National Aeronautics and Space Administration's Gravity Recovery and
Climate Experiment (GRACE) allows scientists of various disciplines to analyze and map …

Precision measurement tools are compulsory to reduce measurement errors or machining
errors in the processes of calibration and manufacturing. The laser interferometer is one of …

We present a comprehensive simulation of the spatial acquisition of optical links for the LISA
mission in the in-field pointing architecture, where a fast pointing mirror is used to move the …

Abstract The Event Horizon Telescope (EHT) is a ground-based array of Very Long Baseline
Interferometry (VLBI) telescopes designed to image the event horizon of black holes. To …
