Abstract

PURPOSE: To measure the thickness without contacting with the measured object, by measuring the extent of movement detected with the scattered beams through the movement of the detector in the direction of the thickness in which the scattered beams from the measured object are received through the emission of radiant rays from the beam source.
CONSTITUTION: The radiant ray source 2 is located on the measured object 1, and radiant rays A are emitted to the measured object 1 from the opening 4 of the shielded object 3. The radiant ray detector 5 is enclosed with the shield material 6 so that the scattered beams B can be incident from one direction only, the detection of scattered beams is made while moving the detector 5 in parallel with the direction of the thickness to measure the extent of movement P in which the scattered beams can be detected. Since the extent of movement P which can detect the scattered beams B and the thickness x are in geometrical relation according to the Compton effect, the thickness x can directly be known from the extent P. With this thickness measuring method, simple measurement is enabled without contacting the measuring unit on the measured object.
