Embodiment Construction
[0056] In order to make the purpose, technical solution and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present application, and are not intended to limit the present application.
[0057] Non-destructive testing is to use the characteristics of sound, light, magnetism, and electricity to detect whether there is a defect or inhomogeneity in the object to be inspected without damaging or affecting the performance of the object to be inspected, and to give the size, location, and location of the defect. It is a general term for all technical means to determine the technical state of the inspected object (such as whether it is qualified or not, the remaining life, etc.), such as information on its nature and quantity, and is a method that does not damage ...

Abstract
The embodiment of this application disclosure a laser detection device, which is the field of non -destructive detection technology. The first laser is used to generate pulse laser; the second laser is used to generate continuous lasers;Compared with continuous comparison laser; measure the light path to receive continuous measurement laser and adjust the light path of continuous measurement laser; compare light road adjustment circuits to receive continuous comparison laser and adjust continuous comparison laser light roads; detect components; wherein the pulse laser is used for the pulse laser for the useScan the surface of the measured objects to cause the measured objects with the same frequency vibration; continuous measurement laser is used to scan the surface of the measured object, and continuous reflection laser is formed after the vibration of the measured object is superimposed.Laser and continuous comparison laser interference form interference laser. The detection component is used to receive the light strength of interference laser and convert it into a electrical signal, which can detect the surface and internal defects of the measured objects.
Description
technical field [0001] The present application relates to the technical field of non-destructive flaw detection, in particular to a laser flaw detection device and a laser flaw detection method. Background technique [0002] Non-destructive testing is to use the characteristics of sound, light, magnetism, and electricity to detect whether there is a defect or inhomogeneity in the object to be inspected without damaging or affecting the performance of the object to be inspected, and to give the size, location, and location of the defect. It is a general term for all technical means to determine the technical state of the inspected object (such as whether it is qualified or not, the remaining life, etc.), such as information on its nature and quantity, and is a method that does not damage or affect its future use on materials or workpieces. A means of testing for performance or use. [0003] In related technical fields, there are mainly two methods currently used for non-cont...
