发明名称 Web inspection calibration system and related methods
摘要 Systems and methods for calibrating a web inspection system using data from a calibrated point sensor, using a frequency spectra-based analysis. A sensor measures a web property of interest, which is then converted into the frequency domain, as is information from a web inspection system. A correlation model is then created to allow calibration of the web inspection system.
