通过对KCLO3晶体的110生长晶面的透射光谱的测试,发现在平行检偏的情况下,KCLO3晶体的偏光干涉会随其厚度和入射角的增加而逐渐消失,并且存在消偏光干涉特性的平面。这些现象表明,KCLO3晶体中的双折射光束电矢量的振动方向与入射的线偏振光电矢量的振动方向间夹角,随晶体的方位而改变。
By measuring the transmission spectra of 110 grown crystal planes of KCLO3 crystal, it was found that the polarization interference of KCLO3 crystal gradually disappears with the increase of its thickness and incident angle in the case of parallel detection, and there is a plane of depolarization interference . These phenomena indicate that the angle between the vibration direction of the birefringent beam electrical vector in the KCLO3 crystal and the vibration direction of the incident linearly polarized electrical vector varies with the orientation of the crystal.
