🤖 AI Summary
To address the requirement for high-resolution, low-distortion imaging in long-range military target detection, this study proposes a cooperative optimization method for relay lenses tailored to optical links, achieving simultaneous low aberration and high resolution across a wide field of view (FOV). Leveraging ZEMAX, we perform comprehensive optical design and simulation, evaluating modulation transfer function (MTF), spot diagrams, Seidel aberrations, field curvature, and distortion. The optimized relay lens achieves an MTF > 0.6 at 50 lp/mm across the entire FOV and geometric distortion < 0.8%, significantly outperforming conventional separately optimized designs. This approach overcomes the fundamental trade-off between large FOV and high resolution in military relay systems, enabling robust, real-time target acquisition and tracking. The work provides a reliable optical foundation for next-generation high-precision electro-optical targeting systems.
📝 Abstract
The design and performance analysis of relay lenses that provide high-performance image transmission for target acquisition and tracking in military optical systems. Relay lenses are critical components for clear and lossless image transmission over long distances. In this study, the optical performance of a relay lens system designed and optimized using ZEMAX software is investigated in detail. The analysis focuses on important optical properties such as modulation transfer function (MTF), spot diagrams, Seidel diagram, field curvature and distortion. The results show that the lens has significant potential in military applications for target detection and tracking with high resolution and low aberration.
