Abstract

The invention discloses an optical axis consistency calibration method of an airborne multi-optical axis optical load, and belongs to the technical field of optical calibration. The calibration operation of the prior art is complicated, the difficulty is large, and the labor intensity is high. The optical axis consistency calibration method comprises the steps of: arranging a main laser auto-collimator and an auxiliary laser auto-collimator in front of a machine body; making the optical window of an aiming device of an airborne fire force control system opposite to the optical window of the main laser auto-collimator, and making the optical window of the photoelectric pod opposite to the optical window of the auxiliary laser auto-collimator; completing the coaxial calibration of the aimingaxis of the airborne fire force control system and the optical axis of the main laser auto-collimator; completing the coaxial calibration of the optical axis of the auxiliary laser auto-collimator and the optical axis of the main laser auto-collimator; completing the coaxial calibration of the optical axis of a central photoelectric sensor and the optical axis of the auxiliary laser auto-collimator; and finally, completing the coaxial calibration of the optical axis of each photoelectric sensor and the optical axis of the auxiliary auto-collimator one by one. According to optical axis consistency calibration method, the optical axis consistency calibration can be realized by only adjusting the calibration device and the to-be-calibrated optical load.

Description

technical field [0001] The invention relates to a method for calibrating the consistency of optical axes of an airborne multi-optical axis optical load, which is used for calibrating the optical axis consistency of an airborne multi-optical axis optical load. The multi-optical axis optical load is a plurality of photoelectric sensors. The optical axis consistency means that the respective axes of several photoelectric sensors are parallel to the reference axis of the carrier plane, which belongs to the technical field of optical calibration. Background technique [0002] The sight 1 of the airborne fire control system is set in the cockpit 2, such as figure 1 As shown, the aiming axis of the fire control system is taken as the reference axis of the carrier aircraft. The airborne photoelectric stabilization equipment used in conjunction with the fire control system includes several photoelectric sensors, which are usually installed in a photoelectric pod 3, and according to ...
