Ultrasonic conductivity-gel measurement system using correlation method

Waveform invariance is the basic principle of correlation sonar.A real-time testing system ba-sed on correlation for ultrasonic conductivity-gel is presented.This system is based on virtual oscillos-cope.It controls communication of the virtual oscilloscope through a USB port and is optimized with the multithreading tool of Windows.Several samples are tested,and the results analyzed.This system can steadily measure the sound velocity and attenuation of the conductivitygel.
