摘要:
针对320×240凝视焦平面阵列探测器,设计了一个变倍比为12×的中波光学补偿连续变焦光学系统。该系统由7片透镜和两个反射镜构成,可实现26.7 mm/80 mm/160 mm/320 mm四档变焦,工作波段为3.7~4.8 ?m,满足100%冷光阑效率。设计结果表明,该系统具有结构简单、透过率高、体积小、像质高等优点。
Abstract:
A optically compensated infrared zoom system with a zoom range of 12:1 is designed, based on medium-wave 320×240 staring focal plane array(FPA) detector. The system consist of seven lenses and two reflectors, can realize 26.7 mm/80 mm/160 mm/320 mm four field-of-view at the spectrum region of 3.7~4.8 ?m and satisfy 100% cold shield efficiency. The design results prove that the system has the advantages of simple structure, high optical transmission, small size and excellent image quality.
