Abstract

Optical imaging systems are widely used sensing devices that may be exposed to long-term or harsh environments. On the other hand, there are few studies on the evaluation of the imaging performance of optical imaging systems by environmental aging tests. In this paper, a typical and common environmental testing, damp heat (steady state) testing, is selected to investigate the influence of its imaging quality. It was found that the imaging quality of both undistorted and distorted optical images was significantly degraded after about 20 cycles of damp heat testing. The color error parameters and noise parameters that characterize its image quality are significantly increased. And this decline in image quality is irreversible. This article will provide a reference for rationally evaluating the service life of an optical imaging system.
