摘要 互易原理是电磁学、光学的常用原理之一,是辐射传输理论的基石.当这一理论被用到遥感研究中,相当多的测量数据,尤其是野外测量数据不支持互易原理在传感器像元尺度上的有效性,因而,互易原理被当作检验遥感数据质量标准时,受到测量界的强烈反对.李小文等用几何光学模型证明了互易原理的尺度效应(Progress in Natural Science,1998,8(3):354~358).Snyder对李等的证明提出质疑(Applied Optics,2002,41(21):4307~4313),并试图证明互易原理在遥感中适用的无条件性,文中对Snyder的质疑进行了考察,指出,由于作者忽略了李小文等证明二向反射(BRDF)互易原理尺度效应的重要条件,并不能证明互易原理是无条件适用于遥感目标的研究尺度的,并再度证明,BRDF互易原理存在尺度效应.
