摘要
介绍了一种结构紧凑、F数较低的红外光学系统,系统选用制冷型面阵红外中波探测器。采用纯透射式的Telephoto Lens为初始结构,在满足结构紧凑的条件下实现了F数为1.5,提高了系统的信噪比。系统在3～5μm波段、视场为4°的条件下成像质量良好,达到了设计要求。
Abstract： the system. Due to the compact system, the f/I must below 0.8. So the Telephoto Lens is used for the initialized structure. F# is 1.5 under the compact structure, and the system S/N is improved. The image quality is good enough for the goal of design at 3～5μm band and FOV of 4 degrees.
