Embodiment 1

[0037] like figure 1 As shown, the laser source 2 is a point light source, and the optical assembly also includes a cylindrical reflector 3, a lens 4 and a plane reflector 5, and the laser light emitted by the point light source is expanded into laser light by the cylindrical reflector 3 The flat sheet light is converted into parallel laser light through the lens 4, and the parallel laser light passes through the plane reflector 5 to change its path, and then is reflected twice by the curved surface reflector 6 to form a ruled curved surface laser. Wherein, the reflective surface of the curved reflector 6 is a cylindrical surface, and a laser is used as a laser source. Therefore, in this embodiment, the laser ruled curved surface emitted from the laser outlet 7 is a cylindrical surface, and the ruled lines are consistent with the direction of the laser light emitted by the laser source 2 . In order to achieve the required accuracy of the ruled curved surface, the curved mirro...

Embodiment 2

[0039] like figure 2 As shown, Embodiment 2 is basically the same as Embodiment 1, except that the reflective surface of the curved mirror 6 is a corrugated surface, so that the ruled curved surface of the laser emitted from the laser outlet 7 is a corrugated surface.

Embodiment 3

[0041] like image 3 As shown, embodiment 3 is basically the same as embodiment 1, the difference is that the cylindrical reflector 3 is removed, and the point light source 2 is directly positioned at the focal point of the lens 4 .

Abstract

The invention provides a laser curve scale, which comprises a laser source and an optical assembly, and is characterized in that the optical assembly comprises a curved surface reflector, and laser emitted by a laser source is reflected by the curved surface reflector to form a straight line curved surface laser. The inventions simple in structure, low in equipment investment, low in light intensity loss and simple to operate, and has good practical significance for expanding the light source structure of a laser sheet, simplifying laser measurement operation and improving a laser scribing process.

Description

technical field [0001] The invention relates to a laser generating device, in particular to a laser generating device for marking line positioning. Background technique [0002] The laser has excellent characteristics such as high brightness, high direction and high monochromaticity. These characteristics ensure that the laser beam can be accurately focused to the focal point, generating thousands of degrees or even tens of thousands of degrees of high temperature and extremely high power density, so that the laser can process almost all materials. The laser sheet light source refers to the use of some instrument to adjust the polarization ratio and linear polarization, so that the light source is scattered at a certain angle to form a larger scattered beam. [0003] Laser sheet light sources are commonly used in the fields of PIV (Particle Imaging Velocimetry) and PLIF (Planar Laser Beam Induced Fluorescence Imaging) multi-field measurements, but currently all planar sheet...
