Embodiment 1

[0022] Embodiment 1: Detection of certain areas on the beam cross section

[0023] The first step is to turn on the laser, adjust the height of the lifting rod frame and the support rod according to the center height of the incident laser beam and the size of the spot size so that the laser beam is incident by the iris diaphragm fixed on one end of the guide rail, and then by the iris diaphragm fixed on the other end of the guide rail. The variable aperture exits, and the aperture is adjusted according to the size of the incident beam, so that the beam just passes through completely;

[0024] The second step is to fix the alignment table without the beam quality analyzer on the translation platform, and adjust the lifting platform and the translation platform in the two-dimensional direction so that the beam can also pass through the variable beam fixed on the mobile platform. Aperture, which ensures that when the platform is moved on the guide rail, the beam can always pass t...

Embodiment 2

[0026] Embodiment 2: Realize the tracking measurement in the beam propagation direction

[0027] The first step is to turn on the laser, adjust the height of the lifting rod frame and the support rod according to the center height of the incident laser beam and the size of the spot size so that the laser beam is incident by the iris diaphragm fixed on one end of the guide rail, and then by the iris diaphragm fixed on the other end of the guide rail. The variable aperture exits, and the aperture is adjusted according to the size of the incident beam, so that the beam just passes through completely;

[0028] The second step is to fix the alignment table without the beam quality analyzer on the translation platform, and adjust the lifting platform and the translation platform in the two-dimensional direction so that the beam can also pass through the variable beam fixed on the mobile platform. Aperture, which ensures that when the platform is moved on the guide rail, the beam can...

Abstract

The invention provides a position-adjustable laser alignment detection device. The position-adjustable laser alignment detection device comprises a sliding part, an alignment part, a two-dimensional moving part and a laser detection pat. The sliding part comprises a base, guide rails and sliding blocks. The alignment part comprises bottom plates, lifting bar frames, supporting rods, diaphragm seats and variable diaphragms. The two-dimensional moving part comprises a bottom plate, a lifting table and a horizontally-moving table. The laser detection part comprises an alignment table and a laser detector. The laser detector can be an optical fiber coupler or a beam quality analyzer or an energy meter probe. The device has the advantages of being low in cost, simple in operation and capable of facilitating positioning, and can be flexibly adjusted according to experiment conditions, and work efficiency is improved.

Description

technical field [0001] The invention belongs to laser detection, in particular to a position-adjustable laser collimation detection device. Background technique [0002] With the continuous development of laser science and technology, laser plays an increasingly important role in the fields of communication, medical treatment, national defense and manufacturing. In laser detection, laser beam parameters at different distance positions are often required. The traditional laser detection device needs a lot of manual adjustment time in the alignment and positioning of the beam, and it is difficult to meet the flexible requirements in the test process, which brings great difficulties to the measurement. Contents of the invention [0003] The invention proposes a position-adjustable laser collimation detection device, which overcomes the problem that it is difficult to realize laser detection at variable distance positions in actual laser detection. The device has the advanta...
