| 摘 要： | 基于液晶可调谐滤光片(LCTF)的多光谱面阵CCD相机是一种新型的多(高)光谱成像系统,它利用液晶的电控双折射效应和偏振光的干涉原理,在面阵CCD上记录任意一个波长的图像信息.由于LCTF和帧转移型面阵CCD工作方式的特殊性,普通的定标方法不能满足遥感应用的精度需求.提出用积分球+标准探测器的定标系统对相机进行性能检测...

| Abstract: | Multispectral area CCD camera based on liquid crystal tunable filter (LCTF) is a new spectral imaging system, which could record image of one wavelength on the area CCD by utilizing electrically controlled birefringence of liquid-crystal and interference principle of polarized light. Because of the special working principle of LCTF and frame transfer area CCD, the existing radiometric calibration method can not meet the precision need of remote sensing application if it is used for LCTF-camera. An improved ... |
