Abstract:
A peak visualization enhancement system for use with a non-destructive inspection (NDI) instrument using a digital display which replicates the haloing effect of analog cathode ray tube (CRT) displays. A peak detection algorithm is provided which intelligently selects the peak values from within the uncompressed digitized waveform while taking measures to prevent noise spikes and the like from being identified as valid waveform peaks. The digital display then highlights the identified peaks, or a subset of the identified peaks, on the compressed waveform display. In this way the effect of bright spots (halos) about the zero slope points on a waveform displayed on an analog CRT is replicated in a digitally compressed waveform display.
