The variation of the film composition can be monitored by using the method of spectrum analysis during the film deposition ( for the intensity of the persistent line is proportional to the particle density of the element in the vacuum chamber ) . the measurement of the transmission spectrum of the film on a transparent substrate can be used to calculate the film parameters , such as refractive index , extinction coefficient and the thickness of the film . therefore , the combination of the two methods would be helpful to on line monitoring the film constituents and the optical paramenters in the preparation of thin films
在制备薄膜的过程中，利用光谱分析的方法，以放电光谱特征谱线强度的变化来反映相应物质成分的变化，以连续光谱光源发出的光透射过薄膜的透射率的变化，来反映薄膜的厚度、折射率、吸收系数等光学参数的变化，从而达到在制膜过程中，对薄膜的成分、厚度等参数进行在线监控的目的
