Abstract
The Head-up Display is a kind of airborne collimation display system, the parallax will directly affect the collimation accuracy, in order to ensure the pilot to obtain accurate collimation data, the image source must be placed at the best image plane in the assembly process, to get the minimum collimation error. The traditional alignment process is to adjust the position of the image source repeatedly until finding the minimum value of parallax by the method of "swinging head" . This paper analyzes the mathematical relationship between the position of the image source and the parallax of the head-up display optical system, and presents a method for determining the optimal image plane, which can provide support for the alignment of high precision optical systems, it can effectively improve the assembly precision and assembly efficiency, and has high value of popularization and application.
