Embodiment Construction

[0037] Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited by the embodiments set forth herein. Rather, these embodiments are provided for more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

[0038] The propagation path of the laser is radioactive, that is, the farther the propagation path is, the larger the spot formed by the laser is, and when the energy is constant, the energy density of the laser is inversely proportional to the area of ​​the spot. The energy density of the laser is related to the detection effect of the laser. Therefore, in order to evaluate the detection effect of the laser at different distances, ...

Abstract

The invention discloses a laser energy detection device and a detection method thereof. The laser energy detection device comprises: an emission unit which is used for outputting a laser with fixed energy; an attenuation unit used for attenuating the laser output by the emission unit and outputting the attenuated laser, moving relative to the emission unit so as to adjust the energy of the attenuated laser; and a monitoring unit used for performing energy monitoring on the attenuated laser. According to the invention, the attenuation unit is adopted to controllably attenuate the original laseroutput by the emission unit, so that the lasers with different energy densities can be simulated, the purpose that the energy densities can be continuously adjusted is achieved, the situation that the quality of the lasers is affected by changing the lasers output by the emission unit can be avoided, the accuracy and reliability of the detection effect are guaranteed, and components of the wholedevice are simple, convenient and easy to achieve.

Description

technical field [0001] The invention relates to the field of laser detection, in particular to a laser energy detection device and a detection method thereof. Background technique [0002] With the development of laser technology, lasers have been widely used in many fields, especially laser light sources in certain bands play an important role in the field of laser detection. Because the energy density of the laser beam output by the laser changes with the change of the laser transmission distance, the effect of laser detection also varies with the increase of the distance. Therefore, in order to evaluate the laser detection effect at different distances, it is necessary to detect the laser light at different distances, but this method is not only time-consuming and laborious, but also difficult to implement in the actual operation process. [0003] In the related art, the laser characteristics under different detection distance conditions are simulated by continuously adj...
