Aiming at the infrared detection requirements of UAV-borne miniature optoelectronic pods, a long-wave infrared optical imaging system for refrigeration detector applications was designed and developed. A Newtonian folded structure replaces the commonly used cassette structure, and the image quality correction of a larger field of view is realized by simplifying the structure of the main telescope and adding an aspherical surface to the correction mirror group.
The main system adopts an all-aluminum optomechanical structure design, and the optical components of the whole system are processed by single-point diamond turning technology, which reduces the difficulty of processing, assembly and development and development costs; 100% cold screen effect design is realized through secondary imaging, which reduces the infrared thermal background, which is beneficial to improve the sensitivity of the system. The optical system has the characteristics of small size, compact structure and excellent image quality.
The system's final installation and commissioning test results show that the image quality meets the design expectations and meets the requirements of the project's technical indicators. This paper has certain reference significance for designing and developing a compact infrared optical system for infrared detection similar to the UAV-borne miniature optoelectronic pod.
