Laser flare measuring device and measuring method thereof

Abstract

The invention relates to a laser facula measuring device and a measuring method thereof. The device consists of a DMD micro-mirror array, a digital camera, an exposure control unit and a picture digital processor. The exposure control unit is provided with two output ends which respectively output signals to control the DMD micro-mirror array and the digital camera; and the input end of the picture digital processor is connected with the video signal output end of the digital camera. In the method, DMD micro-mirror array components are utilized, so the characteristics of an incident light path can be changed at different times and in different regions so as to accurately control the exposure process and obtain a laser beam detection image with high dynamic range; and by means of data processing, diameter, ellipticity, position, center, three-dimensional outline, power, and other parameters of the facula can be obtained. As the whole process happens within a short time, the defect that the position and the energy state of the laser facula changes as time goes by can be avoided, and light beam quality of the laser beam can be more accurately measured.

AI Technical Summary

Benefits of technology

This technology uses an optical system called this inventor's micromirre mirror (MOM) array that allows for precise adjustment over different angles during operation without affecting how well they work at all times. It can detect both linearly polarized or circularly polarizing beams simultaneously while also measuring their size distribution. By doing these measurements on multiple images taken from one same location, we get better understanding about the properties of the lens used by the MONOX machine compared to traditional methods like film cameras.

Problems solved by technology

This patents discusses methods for accurately determining the size (or radius) of a specific part called a "beam". These techniques involve scanning a special kind of laster along one axis while maintaining focusability over another plane. They aim towards improving accuracy and efficiency in detecting small objects like puls marks from laser sources. Additionally, they provide technical means for studying laser radiation patterns and their impact on measurements.
