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...
In this paper, we study the behavior of monochromatic visible light as it propagates through a birefringent quarter-wave plate based on full-wave simulation. Results reveal a transformation of light from linearly polarization into circular polarization upon emergence from the plate. Vice versa for ...

Along with the insertion loss, the most important figure of merit for a quarter-wave plate is the purity of realized circular polarization. The handedness and purity of the circular polarization is commonly expressed in literature using normalized Ellipticity χ, as defined12 below. χ = 2...
Common Waveplate Types and Applications The most common types of waveplates are quarter-wave plates (λ/4 plates) and half-wave plates (λ/2 plates), where the difference of phase delays between the two linear polarization directions is π/2 or π, respectively, corresponding to propagation ph...
Waveplates or Phase Retardation Plates, Retarders are polarizing optics used to manipulate the polarization state of the transmitted light without attenuating, deviating, or displacing the light. The working principle of a waveplate, or a retardation plate, is to utilize the birefringence of certain...
