AI Technical Summary
In existing space laser ranging systems, optical axis parallelism errors lead to ranging failures, and existing calibration methods increase system weight or complexity, failing to effectively address optical axis variations caused by factors such as mechanical impact and vacuum.
By introducing an offset into the initial optical axis center coordinates, traversing the tracking center area of the two-dimensional tracking mechanism, and using laser echo to determine the effective center, online calibration is achieved, correcting optical axis parallelism errors and avoiding the addition of extra equipment and weight.
It enables on-orbit online calibration, simplifies the calibration process, is applicable to non-cooperative or moving targets, reduces system complexity and cost, and is beneficial for lightweight design.
