Based on composite materials and various internal injuries have different dielectric properties
visual NDT is carried out by using planar capacitance array sensor.Discuss system constitution and measuring principle
analyze the factors that influence measurement effect and design signal conversion and acquisition and processing circuit.Based on simple excitation-measurement model and conjugate gradient algorithm
comparative analysis on simulation and experimental results are carried out.Experimental results verify the feasibility and effectiveness of internal defect inspection of composite materials by using planar capacitance sensor array based on capacitance sensitive mechanism.
