Abstract

Curved LED screens are widely used in modern virtual filming and broadcasting technology, however, traditional planar imaging lenses are difficult to handle curved screens, resulting in image distortion and information loss. In order to solve this problem, this paper proposes an optical lens design method oriented to the principle of spherical screen imaging, which can project curved screen contents onto a planar sensor without distortion. The special lens designed using Zemax optical design software adapts to the curvature of the screen to achieve complete capture of the entire curved screen content. The lens consists of 8 pieces, F number is 5.6, focal length is 46.14mm, and the total length of the system is 121.65 mm. The experimental results show that the lens can achieve high-quality image capture on the curved LED screen, improve the imaging effect in the virtual filming and broadcasting, and expand the scope of application of the optical design, which provides a new technological possibility for the multimedia display and interactive entertainment in the future.
