In order to solve the problems of large size, heavy quality, and high cost of traditional photoelectric imaging equipment, two independent design "nodes" of optical system design and image restoration on the whole link of photoelectric imaging are integrated based on the idea of global optimization of computational imaging. First, the difficulty of image restoration with different geometric optical aberrations is analyzed. Then, an optical transfer function that is easy to be processed by the image restoration algorithm is designed through the iterative method of optical-image global automatic optimization. Finally, the output blurred image of single lens and three lenses optical system with global optimization and their restoration quality are analyzed and evaluated. The results show that compared with the optical output blurred image, the contrast, sharpness, and edge retention coefficient of the restored image have been improved to a certain extent. The correction pressure is allocated to the image restoration process to reduce the design pressure of the optical system, thereby simplifying the structure of the optical system.
