红外导引头光学系统的低温补偿是解决光学系统和导引头的低温性能的一种有效方法。从红外导引头研制到设计定型,光学系统的低温一直是个突出的问题,也是导引头技术中的关键问题。随着科研的深入发展和当今武器系统的必需,导引头进入设计定型阶段提出了-40℃的低温要求,然而,由于光学系统在-40℃时散焦量很
Low temperature compensation of the infrared seeker optical system is an effective way to solve the low temperature performance of the optical system and the seeker. From the infrared seeker developed to the design of stereotypes, the low temperature of the optical system has always been a prominent issue, but also the key issue in seeker technology. With the deepening of scientific research and the necessity of today’s weapon system, the seeker enters the design stereotype stage and puts forward the low temperature requirement of -40 ° C. However, since the optical system has a great defocus amount at -40 ° C
