摘要
针对口径为300 mm的三种不同面型整流罩,利用衍射光学元件实现了整流罩像差校正。进一步设计了后端成像系统,与像差校正后的整流罩组成共形衍射成像系统。该系统在1.5~1.6μm波段范围、±1°瞬时视场、±20°扫描视场内实现了良好的成像质量。
The diffractive optical element is designed to correct the aberration on the inner surface of the fairing of 300 mm aperture and three different shapes.The imaging system is also designed and the well imaging quality obtained for±1°instantaneous field of view and±20°scanning field of view in the wavelength range of 1.5~1.6μm.
