Abstract: Titanium dioxide (TiO2 ) is often used as the film material covered on the bottom material .In order to measure the layer thickness of TiO2 coating , the vertical direction of Raman spectra of one‐dimensional mapping technology is used .The data are calculated according to the intensity of rutile A1 g vibration ,located at the 610 cm-1 .The result shows that the thickness of rutile film is 25 μm ,which indicates the Raman mapping is a nondestructive method for measuring film thichness .
