双视场红外光学系统被动无热化设计

摘要

Temperature change could cause the degradation of imaging quality of infrared optical system.In order to improve the adaptability of airborne infrared optical system and ensure steady image quality of the infrared optical sys-tem in complex airborne environment,an athermalization design of dual field infrared optical system was proposed.The key technical indexes and requires of this system are given,and the theory and realization method of the system are ex-plained.Zoom theory and athermal technology are applied in this system.%温度变化会导致红外光学系统的成像质量差，为提高机载红外光学系统的环境适应性，保证红外光学系统在机载动态环境中能够稳定成像，提出了一种双视场红外光学系统无热化设计，给出了系统的主要技术指标和要求，说明了系统的原理和实现方法。
