Abstract

The invention provides a calibration device and a calibration method for transmitting and receiving optical axes of a common-aperture telescope. The calibration device comprises a light source, an imaging detection system, a first reflector, a second reflector, a third reflector, a transmission sighting piece, an electric adjusting mirror, a spectroscope, a tracking quick reflector, an on-board laser transceiving device and a relay transmission optical path, wherein the light source, the imaging detection system, the third reflector, the transmission sighting piece and the electric adjusting mirror are arranged below the telescope; and the first reflector, the second reflector, the spectroscope, the tracking quick reflector, the on-board laser transceiving device and the relay transmission optical path are arranged above the telescope. The calibration device and the calibration method can realize efficient calibration of the transmitting and receiving optical axes of the common-aperture telescope, the optical path calibration method is simple, quick and high in precision (depending on resolution of the on-board laser transceiving device and the imaging detection system, generally can be up to mu rad magnitude order), manual operation is not needed, the optical path calibration time requires about a few minutes, and the optical path detection efficiency of the telescope system is significantly improved.

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...
