Effect of Focusing Mechanism Backlash on Auto-Focus and Algorithm Optimization in Infrared System
This paper introduces the basic principle of auto-focus technology in infrared systems, and analyzes in detail the influence of focusing mechanism backlash on the traditional auto-focus algorithm. A variety of optimized schemes are proposed, and the applicability and stability are fully considered. Finally, an experiment is designed to verify the feasibility of the algorithm which realizes fast, stable and accurate auto-focus, and the algorithm can be used in engineering practice.
