Methods for improving imaging quality of a small-distance high-speed rotational reflection tracking system

The imaging quality of a rotational reflection high-speed tracking system is greatly affected by the optical characteristics of the reflector and the depth of field limitations of the imaging system, especially for tracking systems working in small distances. In order to improve the imaging quality, this paper focused on two factors that affect the imaging quality: double vision caused by the optical characteristics of reflectors and blurring caused by the depth of field of imaging systems. This paper quantified the impact of these two factors on imaging through theoretical analysis, proposed a method of changing the hardware position, and conducted a simulation and experiments. The results show that the proposed solution in this paper can effectively improve the imaging quality of the system. The content studied in this paper has certain significance in the field of high-speed tracking of rotating reflectors and can provide reference for relevant researchers.
