“…Zoom-focusing telephoto imaging systems have the advantages of no central obscuration, long focal length, and high transmission. Therefore, they have been widely used in imaging applications such as remote sensing [1], telephoto optical imaging [2], and infrared imaging systems [3][4][5][6][7][8][9][10][11][12][13]. The introduction of zoom imaging focusing telephoto system ensures that when an optical system requires a low FOV and large F-number, the image quality will not be degraded by various aberrations [14].…”

The optical design involves a zoom optical system, specifically involving a telescopic objective lens system with a wide range of zooming without mechanical motion, which is used to solve the shortcomings of existing zoom telescopic objective lens systems that either require multiple liquid lens combinations for focusing, or need to change the mechanical distance between lens components for focusing. The telescopic objective lens system with a wide range of zooming without mechanical motion includes a double-liquid lens, a fixed-focus telescopic objective, focal surface photosensitive element, and electronic control device. The optical design adjusts the curvature of the middle interface of the dual liquid lens through an electronic control device, and changes the optical focal power of the double liquid lens to achieve high-efficiency and large-range focusing of the telescopic objective lens system.
