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
在制備薄膜的過程中，利用光譜分析的方法，以放電光譜特征譜線強度的變化來反映相應物質成分的變化，以連續(xù)光譜光源發(fā)出的光透射過薄膜的透射率的變化，來反映薄膜的厚度、折射率、吸收系數等光學參數的變化，從而達到在制膜過程中，對薄膜的成分、厚度等參數進行在線監(jiān)控的目的
