Non-destructive crack testing method for airframes using X-rays involves using digital camera to receive image on other side of article from source

摘要

The method of non destructive crack testing of airframes involves placing an X-ray source on one side of the frame and a digital camera on the other side. The camera image is analyzed in real time using a microcomputer (28). If the image is non-usable, the source is immediately adjusted and a second image taken. The source wavelength can be adjusted, the source intensity, or the exposure time. Claims include an apparatus for carrying out the method.
