Abstract

The invention discloses an optical imaging system which is suitable for acquiring an image of a groove at the end part of a tubular element. The optical imaging system comprises an annular light component, a coaxial light component and a shooting component, wherein the annular light component comprises an annular light source, and the annular light source is suitable for carrying out annular lightillumination on the groove; the coaxial light component comprises a coaxial light source, and the coaxial light source is arranged behind the annular light source, and is suitable for carrying out coaxial light illumination on the groove, wherein the optical axis of the coaxial light source is coaxial with the optical axis of the annular light source; and the shooting component comprises a cameraand a lens connected to the camera, and the shooting component is arranged behind the coaxial light source and is suitable for acquiring the image of the groove of the tubular element. The optical imaging system disclosed by the invention can accurately, clearly and comprehensively display the defects such as burrs, chipped edges and fractures on the slope, so that the accuracy of groove defect detection is improved.

Description

technical field [0001] The invention relates to the technical field of groove detection, in particular to an optical imaging system. Background technique [0002] As a clean, efficient, and pollution-free clean energy, nuclear energy has been widely used in military, production, and economic fields. Nuclear power generation has become an irresistible trend. Due to the characteristics of less residual waste, high energy utilization rate and high maturity of industrial application technology, heavy water reactors are widely used in nuclear power systems around the world. Nuclear fuel rods are the basic elements of heavy water reactors, and the quality of their processing and production is directly related to the normal operation of nuclear power plants. Because zirconium materials can still maintain good metal properties under high temperature and high radiation conditions, zirconium alloy tubes are generally used to wrap nuclear fuel to prevent fission products from overflo...
