... Abstract Measuring the thickness of thin films can be accomplished in many ways. This article focuses on the optical method of single-wavelength ellipsometry, two multiple-wavelength methods of reflectometry and spectroscopic ellipsometry for measuring the thickness of thin films. The general...

... sensors and processes. For example, when vibration sensors are mounted to online monitor FFF processes, the process-aware statistical features in the time domain can be extracted for process monitoring ( Ref 52 ). Similarly, another feasible strategy is converting the sensor signals to the frequency...
