- Abstract:
- A Virtual-Instrument for Air-Coupled Ultrasound Non Destructive Testing applications based on Psuedo- Noise Sequences is presented. The instrument is designed by means of the LabView software to manage and synchronise a digital input/output module and a virtual oscilloscope and to implement the digital processing required to fully exploit the characteristics of the coded excitation. The Signal to Noise Ratio enhancement assured by this technique with respect both Additive White Gaussian Noise and Quantization Noise is theoretically analysed and experimental verified.
