ABSTRACT:
A penetrating radiation is used to examine a steel bar in a reinforced concrete coordinated with a comparing object. The position and size of the comparing object are known in advance. At first, the steel bar and the comparing object are projected on an imaging device. Then, a magnifying rate of an image size of the comparing object shown on the imaging device is calculated. By using the magnifying rate and by comparing the image sizes of the steel bar and the comparing object on the imaging device, the defect size of the steel bar can be figured out.
