AI Technical Summary
In inter-star laser distance interferometer, due to the delay in beam transmission time and non-ideality of orbital mechanics caused by long distances between stars, the front finger angle changes, which makes the laser beam unable to be accurately received and emitted, affecting the establishment and maintenance of the laser link.
The space scanning technology based on the fore-finger angle mirror is adopted, and the outgoing laser beam is controlled to perform sub-region space scanning through the fore-finger angle mirror, and combined with the driving of a large-mass one-dimensional overall pointing deflection mechanism and satellite platform, the sub-region scanning of uncertain areas is realized until the remote satellite receives the laser beam and corrects its direction.
Through fast space scanning technology, inter-star laser links can be quickly established and maintained, reducing time costs and propellant consumption costs, and making full use of the limited beam pointing control resources on the star.
