Furthermore, when infrared interferometry is used to measure epi-wafer thickness, the unique two-layer structure of the epi-wafer often leads to secondary or multiple interferences, resulting in the presence of more than three peaks in the periodogram. These problems pose significant challenges to the final calculation and thickness extraction. Near InfraRed FILM thickness PROfile (NIR-FILMPRO) is an optical technique for non-intrusive measurement of water film thickness. The technique is based on absorption of NIR light. A passband filter centered at 1612 nm was selected to measure isothermal gravity-driven films flowing on a vertical wall with sand blasted surface.clearly seen in the FTIR spectrum of a 1.5 mil thickness poly-styrene sample shown in Figure 1. Figure 1. FTIR spectrum of 1.5 mil polystyrene film showing “fringing effect”. From this fringing effect we can calculate the thickness of the film using the following equation; b = 1/2n x N / ( υ 1 - υ 2) where; b = film thickness
The correct solution: infrared sensors. You may be wondering; is there not a single method for thickness measurements of oil that works all the time? Good news, there is! The answer is infrared sensors. More specifically: infrared sensors with a middle-range wavelength. As it turns out, all oils react to a specific wavelength of infrared light.
