Design of Array Photo-electricity Non-destructive Detection Instruments

Aim\ To research a new instrument of Non destructive detecting the quality of welding line using a X ray photo electricity array sensor. Methods\ Let X ray irradiate on a x ray photo electricity array sensor through the object, to collect the message density of welding lines, and send to a computer for image processing. Results\ The instrument can effectively detect the density of welding lines, and faults such as air holes and dregs by using low power X ray. Conclusion\ It is shown in experiments that this instrument can detect wide dynamic scope and also detect the dose of X ray, and detect other physic quantity after changing photo electricity array sensors.
