Fast Alignment and Test Methods of Optical Axis Parallelism of UAV Target Positioning System

In UAV target positioning system, optical axis parallelism is an important parameter. It must be checked and adjusted to the accurate status regularly. A fast alignment and test system of optical axis parallelism used for airborne opto-electric stabilized platform is introduced in this paper. It describes the principle and the process of the two optical axis parallelism alignment in the system. Besides, two fast test methods of optical axis parallelism for field are introduced, and their relative merits described and compared. The methods are proved to well meet the optical axis parallelism test requirements through engineering practice. Their application is of practical engineering significance, is useful for the shortening of alignment time and cost reduction.
