| titleOfInvention | Device and method for rapidly detecting defects in large-caliber element body |
| abstract | The device mainly comprises a laser, a half-wave plate, a polaroid, a beam shaper, a first imaging lens, a first CCD camera, a second imaging lens, a second CCD camera, a microscope lighting source, an optical fiber, a YZ two-dimensional moving platform, a XYZ three-dimensional moving platform, a scanning synchronous control system and a computer. The invention utilizes the YZ two-dimensional moving platform and the XYZ three-dimensional moving platform to respectively control the light source and the high and low power imaging system to move, thereby avoiding danger and unstable measuring result caused by rapid movement of a large-caliber element. The invention adopts a mode of combining low-power full-aperture laser scattering rapid scanning imaging and high-power fixed-point bright field imaging, not only realizes rapid positioning of the body defect, but also can accurately measure the size of the body defect, and provides reliable basis for element quality evaluation and grading. |
