左旋分子就是使偏振光发生左(即逆时针方向)旋的分子。
A left-handed molecule is one that causes polarised light to rotate to the left (ie, anticlockwise).
基于光的偏振特性、马吕斯定理和法拉第旋光效应，采用同光源双光路检测，实现了大量程直线位移的测量。
Based on characteristics of optical polarizing, Malus law, and Faraday optical rotation, a long-range displacement detector is realized by same light source and double light route.
本文用旋转矢量描述园偏振光的时空动态特征，并由此直接推导出旋光的瞬态规律。
