Abstract

Owing to complex application environments and trends of intelligent perception associated, modern zoom systems with enhanced integration, increased imaging speed, decreased physical size, and improved dynamic adaptive adjustment strategies are required under external disturbances. Upon this requirement, reflective deformable mirrors (DMs, a Micro-Optical Electro-Mechanical System (MOEMS) device), which represent novel optoelectronic devices, have propelled the development of fast zooming and high-resolution imaging systems. In this paper, we design a catadioptric zoom system based on transmission fixed lenses and reflection deformable mirrors. The fixed lenses are used to increase the system field angle, increase the entrance pupil diameter, and balance the off-axis aberration caused by a large field of view. For practical application, we also consider the DMs specifications, e.g., the flexible deformation amount of actuator stroke within the effective diameter range. The system enables continuous zooming in the complete focal-length range at a high zoom ratio (10:1), and the full field of view at the wide-angle position is expanded to 20° × 20°, by improving the zoom sensitivity ability and aberration correction. This optical system is conducive to further establishing a stabilized zoom system with image stabilization ability integrated based on DMs.
