摘要
根据偏光干涉原理,对云母在可见光波段内进行连续波长扫描,得到云母快慢轴两条偏振光的透过率曲线.由两条曲线的相对位置可以判断云母的快慢轴方向,并由透过率曲线计算出云母波片的折射率no、ne,得到整个可见光范围内的折射率.对比光学手册中云母的折射率值,测量误差小于5%.
Abstract
According to the principle of polarization interference,continuous wavelength scanning is performed in the visible light band to obtain two polarization light transmittance curves of the fast and slow axis of mica,which are judged by the relative positions of the two curves.The direction of the fast and slow axis of mica,and the refractive index no and ne of the mica waveplate are calculated from the transmittance curve,and the refractive index in the entire visible light range is obtained.Compared with the refractive index value of mica in the optical manual,the error is less than 5%.
