Abstract

The standard evaluation methods of the imaging quality of optical imaging systems are divided into evaluation methods based on electrical signals and evaluation methods based on images, but the impact of environmental testing on the imaging quality is rarely studied. This paper aims to analyze the imaging quality of a typical optical imaging system before and after the salt mist testing. By studying its imaging resolution and setting up different optical environments, the influence of salt mist testing on its imaging resolution under different optical environments is discussed here. It is found that different illumination conditions have great influence on imaging resolution, and good illumination conditions can effectively improve the resolution of camera products. In the other hand, salt mist aging testing has a great influence on the imaging resolution of the camera products, and longtime exposure to sodium chloride solution has an irreversible effect on the imaging performance of the camera. The tolerance of cameras to salt mist aging test shows two-level distribution. Some products are completely invalid, and some products have good tolerance and no obvious failure.
