摘要
用特征矩阵法研究了薄膜法布里-珀罗滤光片的偏振特性。研究发现:随着入射角增大,s偏振光透射模和p偏振光透射模的波长逐渐分离,但分离的幅度较小;随着入射角增大,s偏振光透射模的透射率作幅度较大的震荡变化,而p偏振光透射模的透射率变化较小;当入射角以1°/100的间隔变化时,可以在透射模波长不变的情况下,使s偏振光透射模的透射率发生显著变化,而p偏振光透射模的透射率基本不变。薄膜法布里-珀罗滤光片的偏振特性可以在角度变化的测量中发挥重要作用。
The polarization properties of thin film Fabry-Pérot filter is investigated by eigen method.With the increase of incident angle,the wavelengths of the transmission modes of s-polarized light and p-polarized light separate gradually,but the separation is small.The transmittance of the transmission mode of s-polarized light vibrates greatly and the transmittance of the transmission mode of p-polarized light vibrates little with the increase of incident angle.When the incident angle changes at the separation of 1°/100,the wavelengths of the transmission mode of s-polarized light and p-polarized light keep unchanged and the transmittance of the transmission mode of s-polarized light changes significantly,while the transmittance of the transmission mode of p-polarized light changes very small.The polarization properties of film Fabry-Pérot filter can play an important role in angle measurement.
