Abstract
As a widely used sensing device, the optical imaging system mainly includes products used in outdoor and indoor scenarios. However, there are few studies on the effect of environmental aging test on the imaging performance of the two types of products. In this paper, typical products used in two different scenarios, outdoor and indoor, are selected to investigate the quantitative impact of the damp heat test on their imaging quality. The investigated parameters used include imaging resolution, color revent and gray scale value. The study found that after about 10 cycles of damp heat test, the imaging quality of optical imaging products used indoors decreased significantly, with a decrease of more than 20% in key parameter. Outdoor use products have good tolerance to environmental testing, and there is basically no big difference. This paper will provide some reference for the rational use of optical imaging systems and the compilation of test standards.
