3results about How to "Eliminate immobility" patented technology

The application relates to the technical field of laser gas detection, and provides a micro laser gas detection module and a gas detection method, which comprise a shell, a gas chamber cavity, a laser emission assembly, a mirror group and a laser receiving assembly. The gas chamber cavity is formed in the shell, the laser emission assembly, the mirror group and the laser receiving assembly are arranged in the gas chamber cavity, the optical axis of the laser emission assembly and the optical axis of the laser receiving assembly are vertically arranged in space, the mirror group comprises a first mirror group and a second mirror group which are oppositely arranged along the depth direction of the gas chamber cavity, the first mirror group is composed of two first plane mirrors which intersect at an angle of 90 DEG, the second mirror group is composed of two second plane mirrors which intersect at an angle of 90 DEG, the vertical distance between the axis line where the two first plane mirrors in the first mirror group intersect and the axis line where the two second plane mirrors in the second mirror group intersect is a first distance. The application can eliminate interference caused by stray light.
