摘要
旋光器是常用的偏光器件之一 ,通常用晶体旋光材料制成 ,其旋转角是不可调的 .本文研制了一种新型可调复合旋光器 ,结构简单 ,其旋转角连续可调 .从理论和实验可看出 ,无论入射线偏振光的振动方向如何 ,出射线偏振光总是相对入射光偏转 2γ .从而克服了一般旋光器的不可调性 ,为科学实验提供了方便 .
The polarization apparatus is one of usual polarizing devices made of crystal optical material,and its' rotation angle is nonadjustable. In this paper, a new type of adjustable compound polarization apparatus is studied. It has the merits of simple structure and continuously adjustable rotation angle. The emergent linearly polarized light has 2γ angle of deflection according to the incident light regardless of polarized direction of the incident light. The adjustable compound polarization apparatus which overcomes the nonadjustable nature of general polarization apparatus provides convenience for the scientific experiment.
