Abstract  The IR imaging system in the field circumstance is affected by the internal equipment dispelling hot and the exterior circumstance temperature changing. The key of all kinds of IR imaging systems' effective working is how to solve these questions such as the machine structure distortion and imaging quality unsteadiness.Based on the IR imaging system features， its temperature adaptability was researched in the machine structure design and optics structure design sections， and a reasonable structure was designed. The last contrast experiments show that the undershooting of the system adopting temperature adaptive design is 17% of that no adopting temperature adaptive design. The system can entireties satisfy the system temperature stability request and can ensure the good imaging quality．

Key words： IR imaging      environment adaptability      heat insulation design      dispelling hot design

红外成像系统温度适应性设计

野外环境下的红外成像既要受到内部设备的散热影响又要受到外部环境的温度变化影响．温度变化导致的红外成像系统的机械结构变形及成像质量不稳定问题关系到各类成像系统能否有效工作．结合红外成像系统的特点，在机械结构设计与光学结构设计两方面对某型红外成像系统温度适应性进行研究，设计了合理的结构形式．后续的对比实验表明本设计在因温度造成的成像脱靶量约为未采用温度适应性设计系统的17%．系统完全能够满足温度稳定性要求，能够保证较好的成像质量．
