However, due to the limitation of test conditions, the current domestic photoelectric imaging system can only perform image quality evaluation in conventional temperature environment and storage test in high and low temperature environment. However, the key indicators of the imaging quality that determine the performance of the optoelectronic imaging system, such as transfer function and resolution, cannot be assessed under boundary temperature conditions.

The limitation of test conditions and methods restricts the performance evaluation of the photoelectric imaging system, laying hidden dangers for its application and performance in the boundary temperature environment
