Scope

This document describes a three-sensor calibration method for calibrating the absolute sensitivity and frequency response of three reversible acoustic emission sensors of the same type by using reciprocity technology.
This document describes a two-sensor calibration method for determining the absolute sensitivity amplitude-frequency response of an acoustic emission sensor to be calibrated, using a sensor whose emission current response has been obtained through the three-sensor calibration method.
This document describes a pulse response calibration method for calibrating the absolute sensitivity pulse response of a sensor by measuring the frequency response obtained through the three-sensor calibration method and then performing a Fourier inverse transform on it to represent the calibration result as a pulse response.
