Abstract
This paper introduces a photoelectric detection system, i.e. the internal surface of the metal tube illuminated by Xenon light through fiber bundle, is imaged on CCD optical receiver by endoscope. The image can be converted to video frequency signal, then this signal can be converted to digital signal by a sampling control system, which processed by a computer. SO the measurement system can clearly display the surface flaws of workspace of complicated construction, and quantitatively measure sorts of flaws by an image processing system.
