将来的高分辨率地球观察成像系统很可能使用自扫描红外探测器。已研制成10～12微米波段的红外成像系统,作为向此方向发展的初步条件。这种系统采用由9元光导碲镉汞/CCD线列,9个前放和1个硅CCD多路传输器集成的焦平面。采用光机扫描技术对景物扫描,并实时产生图像。本文描述了这种系统的成像性能,给出了噪声、响应率、D~*和探测器灵敏度分布的测量结果。文中还讨论了对用于将来美国航宇局遥感方案的更高级探测器阵列的要求。
Future high-resolution Earth observation imaging systems are likely to use self-scanning infrared detectors. Has developed a 10-12 micron band infrared imaging system, as the initial conditions for the development of this direction. This system uses a focal plane integrated with a 9-element light guide cadmium telluride / CCD line array, 9 preamplifiers and a silicon CCD multiplexer. Light machine scanning technology to scan the scene, and real-time images. This article describes the imaging performance of such a system, giving measurements of noise, responsivity, D *, and detector sensitivity distribution. The paper also discusses the requirements for a more advanced detector array for future NASA remote sensing solutions.
