| Abstract: | A multi-channel and high precision ultrasonic-tomography instrument used for concrete testing is developed.Multi-channel ultrasonic signals passing the concrete structures are captured by high speed and high precision signal acquisition circuit.Tomography result of concrete is produced based on the time of ultrasonic signals passing the concrete.In the detection test of the concrete sample,the tomography image produced by the system clearly shows the inner structure of test sample.Experimental result shows ... |
