Optical design of uncooled high zoom ratio continuous-zoom lens

  • 摘要: 针对长波非制冷氧化钒320240像元焦平面阵列探测器,像元间距25 m25 m,采用变焦距光学系统设计原理,引入非球面和衍射面设计技术进行像差平衡,设计了长波红外连续变焦光学系统。该系统工作波段为8 m~12 m,视场为2.86~50连续可变,F数为1.2,变倍比为18∶1,在整个变焦范围内,光学调制传递函数在0.5以上,接近衍射极限,并且全视场能量70%集中在探测器的一个像元内。整个变焦光学系统仅使用一种红外材料(单晶锗)进行像差矫正。
    Abstract: Aiming at the long-wave uncooled vanadium oxide focal plane arrays ( FPA) detector with 320240 pixels and 25 m25 m pixel pitch, an long-wave infrared continuous zoom optical system is designed, based on the optical zoom theory, as well as the aspheric and diffractive aberration balancing method. Its spectral range is 8 m~12 m, field of view(FOV) is 2.86~50,F number is 1.2 and zoom ratio is 18∶1. In the all optical zoom range, the modulation transfer function (MTF) is above 0.5 approaching the diffraction limit, and 70 % of the encircled energy is concentrated in one pixel of detector. Moreover, only one common infrared material of germanium is used to balance the aberration.
