A device for analyzing a transient waveform

摘要

A device for analyzing a transient waveform is provided with a computation unit which analyzes the observed transient response waveform as an input adaptive type autoregressive model consisting of a linear function of regressive coefficients dependent upon material parameters or upon material parameters and material spectra. It can perform a rapid and accurate analysis of the transient response waveform observed through the incidence of pulse laser beams, promoting searches into the prime process of material changes.
