摘    要:红外目标模拟器由红外目标图像发生器和投影光学系统组成。该红外光学系统是一个要求与2个导引光学系统的光学技术参数相匹配的长焦距、大视场和具有像方远心光路的中红外光学系统。叙述用于红外目标模拟器的红外耦合光学系统的设计原理,提出它与导引光学系统一起可组成放大倍率M=4.5×的红外投影光学系统,并指出IR CRT产生的图像通过红外投影光学系统可成像在导引接收器上。针对给出的红外耦合光学系统的设计特点和技术要求,光学材料选取硅(Si) 锗(Ge) 硅(Si),采用简单的柯克三片式结构完成光学系统设计。设计评价结果表明,该系统的光学性能和成像质量均满足设计指标要求。

关 键 词:中红外耦合光学系统  光学设计  像方远心光路  目标模拟器

Abstract:The infrared target simulator is composed of infrared target image transmitter and the optical projection system.The infrared coupling optical system is a middle-infrared system with a long focal length, larger field and telecentric beam path in image space,which is required to match with the parameters of two homing optical systems.The optical design of infrared coupling system applied to infrared target simulator is presented in this paper.The combination of infrared coupling system and homing optical system can constitute an infrared projective optical system with a magnification of 4.5.The IR-CRT image can be projected on the receiver of homing optical system through an infrared projective optical system.Si-Ge-Si is selected as optical material based on the design characteristics and technical specification of infrared coupling system,and the design of the optical system with a Cooke three-lens structure has been implemented.The design and assessment results indicate that the optical performance and image quality of the system can meet the design specification.
Keywords:middle-infrared coupling optical system  optical design  telecentric beam path inimage space  target simulator
