Title:
OPTICAL RESONANT CAVITY AND GAS ABSORPTION SPECTRUM DETECTION DEVICE
Document Type and Number:
WIPO Patent Application WO/2024/060026
Kind Code:
A1
Abstract:
An optical resonant cavity (100) and a gas absorption spectrum detection device. The cavity comprises: a first cavity mirror (101) and a second cavity mirror (102); the first cavity mirror (101) comprises a plurality of reflection points, and at least one of the reflection points of the first cavity mirror (101) is an input reflection point (103); a reflective surface of the second cavity mirror (102) is arranged opposite from a reflective surface of the first cavity mirror (101), and together with the first cavity mirror (101) forms an optical resonant cavity (100); the second cavity mirror (102) comprises a plurality of reflection points, and at least one of the reflection points of the first cavity mirror (101) or second cavity mirror (102) is an output reflection point (104); a light beam is transmitted into the optical resonant cavity (100) via the input reflection point (103), and after being reflected at least four times between the reflection points of the first cavity mirror (101) and the reflection points of the second cavity mirror (102), satisfies a re-incidence condition and enters the next reflection cycle; the cycle is repeated until the energy attenuation of the light beam in the optical resonant cavity (100) is 0.
