摘要: 从几何光学的理论出发,研究波片延迟误差的校正方法。通过研究晶体延迟器件光线入射方向与其延迟量变化的关系,从理论上导出了光线斜入射到波片时波片相位延迟量变化的计算公式,从而证明了可以通过绕与波片光轴平行的轴向或绕垂直于波片光轴的轴向转动波片进行波片延迟误差的校正。用消光法和最小光强法分别对λ/2波片和λ/4波片进行了延迟误差的校正。结果表明,波片的延迟误差可以通过转动波片的方法来消除。Abstract: The method of correcting the retardation deviation of a wave-plate through geometrical optics is studied.By means of exploring the relation of the orientation of incident light and the change of retardation of the crystal device,the formula for calculating the change of retardation of a wave-plate is derived when the incident light is oblique incident.Thus the retardation deviation can be corrected through rotating the wave-plate on the axis direction parallel to the optical axis or the axis direction vertical to the optical axis.The retardation of a λ/2 wave-plate and a λ/4 wave-plate is corrected by means of light extinction method and light minimum method respectively.Thus the deviation of retardation of wave-plate can be corrected by means of rotating.
