摘　　要：首次利用S偏振光的反射保偏特性,采用三腔镜法使S偏振方向的光沿一个方向多次通过手性材料来增大旋光角度的新方法,可较精确地测量旋光性较弱的手性材料的旋光角,实验证实了理论设想。测量结果表明:在光路中放入手性材料后,S方向偏振光在三次循环的情况下,出射光仍几乎保持线偏振的状态,其旋光角度与其循环次数成正比关系。t： A new method which uses ized reflected light is firstly put forward. the polarization maintaining characteristic of S-polarThe rotation angle of light will be enlarged if the Spolarized light passes through the chiral material many times along one direction in the trihedral reflector. The rotating light angel of chiral material with weak rotation can be measured accurately, and the theory is confirmed by the experiments. The result shows that the S-polarized light goes through the chiral material for three times, the output of S-polarized light still retained linearly polarized, and the rotation angle of S-polarized light is in direct ratio with its circulation times.
