1/4波片(wave plate)是利用材料的各项异性特点,对不同偏振方向的光有不同的折射率与传播速度,从而造成两个分量相位差,而将线偏振光转换为圆偏振光,或将圆偏振光转换为线偏振光。 P.S.如果控制材料与厚度使光通过后两个分量直接相差1/2相位,则称为1/2波片或半波片,该波片有其它用途。 动画地址: Circular Pola...
激光器发出的经过偏振片选择后的线偏振光,经过1/4波片后,两个分量产生1/4波长相位差,反射回来后,两个分量的方向和相位差不变,再次经过1/4波片,两个分量再次叠加1/4波长相位差,共1/2相位差,所以合成的光为线偏振光,且偏振方向与原方向垂直,所以无法再次通过偏振片。 总结 1/4波片(wave plate)是利用材料的...

A wave plate is a device used to control the polarization of light. When light is polarized, it is directed in two axes; the angle between the axes, one being designated the fast axis and the other the slow axis, is 45°. A quarter-wave plate transforms linearly polarized light into ...
A waveplate, also called a phase retarder, is an optical element that changes the polarization state of light by generating an optical path difference (or phase difference) between two mutually orthogonal polarization components...
