Description

technical field [0001] The invention relates to the application field of laser technology, in particular to a device and method for calibrating the receiving and receiving optical axes of a common-aperture telescope. Background technique [0002] With the development of photoelectric countermeasures and photoelectric detection technology, in order to ensure the high-precision and fast tracking performance of the target, the common-aperture telescope system based on compound axis control plays an important role. The telescope system not only requires fast and stable tracking of the dynamic target, but also must aim the emission beam at a certain point of the target. The zero-point consistency error between tracking and aiming optical axis will affect the aiming accuracy of the emitted beam in severe cases, resulting in the inability of the telescope system to aim at the target accurately. How to ensure that the transmitting beam is aimed at the target tracking zero point dur...
