Embodiment Construction
[0031] This embodiment solves the shortcomings of the current detection of the straightness of the laser line light source that the human error is large and cannot be truly accepted by the industry. This embodiment provides a comprehensive detection method for the laser line light source, which includes the following steps: 1) In the word Divide the diffusion angle equally within the range of 120° on the projection surface of the laser module to form several areas with equal edge angles;
[0032] 2) Take the intersection point of the edge of the above-mentioned areas and the laser line of the flat laser module on the projection surface, take the midpoint of the laser line between adjacent intersection points as the measurement point, and place the surface at the measurement point Array CCD module and linear array CCD module to obtain the image of the laser line at the measurement point and the position and line width information of the laser line;
[0033] 3) Use the rotating ...

The invention provides a comprehensive detection method of a laser ray light source and a system for achieving the method. An area array charge coupled device (CCD) module and a linear array CCD module are placed on a measurement point simultaneously so as to obtain an image of a laser ray of the measurement point and information of the position and ray width of the laser ray, the width and straightness of the laser ray can be detected accurately, the defect that the circumstance of the laser ray can not be truly reflected caused by personal errors and sampling detection is avoided effectively, detection precision is improved, and detection results can be shown to people visually in a manner of images, and therefore the method and the system are easy to accept and popularize for people, the method is simple in operation, and the system is simple in structure, easy to realize and low in cost.
Description
technical field [0001] The invention belongs to laser detection technology, and in particular relates to a comprehensive detection method of a laser line light source and a system for realizing the method. Background technique [0002] The laser line light source is composed of laser diodes, optical components, metal structural parts and electronic circuits, which can produce red or green visible laser marking lines, and can be widely used in other products such as indoor and outdoor decoration marking positioning. [0003] The line formed by the laser line light source on the projection surface is called the laser line, and the straightness, width, and line quality of the laser line are its main indicators. [0004] Straightness is the quantitative representation of the bending degree of the laser marking emitted by the laser line light source. [0005] Such as figure 1 with figure 2 As shown, set the laser line light source perpendicular to the marking line receiving ...
