ABSTRACT:
The present invention discloses a construction of an industrial endoscope with a sensor which is used for measuring the position and the moving direction of a distal end of said endoscope. The construction comprises a measuring window at said distal end, light-transmitting optic bundles and light-receiving optic bundles, forward ends of said light-transmitting optic bundles and light-receiving optic bundles being opposed to said measuring window, a backward end of said light-transmitting optic bundles being connected with a light source and a backward end of said light-receiving optic bundles being connected with a detector means. By this construction, a reactor can be safely inspected from a distance, preventing damage to said distal end and elimination of potential radiation danger to the inspector.
