| 摘 要： | 针对联合变换相关器对坦克目标进行实时探测跟踪的需求,设计了一种红外变焦光学系统。该系统采用320×240元非致冷焦平面阵列探测器,在8～12μm波段,系统变焦范围为60～240mm,F数为2。通过对系统的优化设计,当最大截止频率为17lp/mm的时候,各视场的MTF调制传递函数均接近衍射极限,成像质量良好,并且系统具有大相对孔径以及结构紧凑等优点,满足了坦克目标跟踪识别的实际应用需求。

| Abstract: | According to the system requirements of tank target detecting and tracking by joint transform correlator,a kind of infrared zoom optical system is designed.The optical system working in 8～12 μm spectral region applies 320×240 pixel uncooled thermal IR focal plane array detector,realizing 60～240 mm continuous zooming and F number of 2.MTF curve of the zoom approaches the diffraction limit in each field of view at the spatial frequency of 17 lp/mm after the optimization,which shows that the imaging quality is good.The system has a large relative aperture and compact structure,and it meets the tank’s actual application requirements of target tracking and recognition. |
