介绍了CMOS APS(有源像素图像传感器) 的原理与结构,并介绍了发展现状。详细分析比较了CMOS 图像传感器相对CCD 的性能特点,讨论了CMOS 图像传感器在空间技术中的可应用领域,尤其是在微纳型卫星遥感成像、姿态敏感方面替代CCD 的应用可行性。
关键词: CMOS 图像传感器; 有源像素传感器; 遥感微型相机; 太阳敏感器; 星敏感器
Abstract : For nano satellite , CCD is difficult to reach the requirements of volume , weight and power consumption in the fields of on2satellite image acquisition such as remote sensing and attitude determination1 CMOS image sensor , with the corre2 sponding characters , provides the potential realization of the image function in nano2sate1 The theory and architectures of CMOS image sensor are introduced , as well as the developing status of it1 The feasibility of its application in the space technology is an2 alyzed , based on the comparison of character of CMOS APS with that of CCD1 All these analysis and studies allow the conclu2 sion that as the CMOS technology and its application technology develop , CMOS image sensor must be a potential replacement of CCD in the field of micro &nano satellite1
Key words : CMOS image sensor ; CMOS APS; miniature camera for remote sensing ; sun sensor ; star tracker
