| 摘 要： | 双色红外光学系统能够同时获取长波红外与中波红外的波段信息,有利于目标的搜索和识别.本文针对红外热像仪的需求,对双视场/双色红外光学系统进行了设计.实现了4.4～5.4μm/7.8～8.8μm双波段同时清晰成像,在F#为2.68情况下,通过切换变倍组完成9°×6.75°/3°×2.25°双视场转换.通过红外材料与光焦度的合理分配实现了折射式被动消热差设计.设计结果表明,系统在-40℃～+60℃工作温度下,像面稳定、像质优良,能够满足红外热像仪的使用需求.

| Abstract: | Dual color infrared optical systems can obtain LWIR and MWIR information simultaneously, which would be good for the target tracking and recognition. As to the needs of the infrared thermography, dual FOV /dual color infrared optical system is designed with simplified optical configuration. Dual color (4.4~5.4 μm/7.8~8.8 μm) clear imaging is achieved, and double view switch (9°×6.75°/3°×2.25°) can be completed by switching variable group when F# is constant(2.68). Through rational distributions of IR material and focal power, the optical passive athermal design achieves. The results indicate that when the systems works on －40℃~60℃,the image plane is stable and the image quality is excellent, which can meet the using requirement of infrared thermographs. |
