WebThermographic signal reconstruction is a processing technique widely used in IRT NDT for enhancing detection of defects and filtering noise [22,23]. The application procedure consists of several steps including the logarithmic transformation of the captured data, the interpolation at early stages and the polynomial fitting, among others. WebUltrasonic receive signals are often close to the electronic noise floor and require high gain amplification before processing and display. Despite electromagnetic compatibility …
