The weak-light phase locking is an important module of the inter-satellite laser interferometric ranging technology, which can amplify the power of the weak-light signal received through a long distance and transmit it back with the same phase. The article introduces and analyzes the principle, research status and noise analysis of weak-light phase locking, providing a reference for further research on weak-light phase locking.
