AI Technical Summary
Technical Problem
Existing gas probes have short optical paths, low absorption, and low sensitivity, which cannot meet the requirements of high-precision testing and are also bulky.
Method used
Employing a multi-reflection structure, the optical path is extended through a combination of planar and concave mirrors. The laser is reflected multiple times within the gas chamber, and signal conversion is achieved using a high-precision photodetector, enabling high-precision detection.
Benefits of technology
It enables long optical path testing within a limited space, improves the detection sensitivity of the probe, meets the requirements of high-precision gas detection, and has a small size.
