- Abstract:
- The multiple reflection cavity is the core component of the laser absorption spectrum gas sensor, and its structure and performance directly affect the sensitivity and stability of the entire equipment. The design scheme and working principle of multiple reflection cavities mainly used domestically and internationally, such as White cavity, Herriott cavity, CEAS cavity, were analyzed. 96 reflection cavities were designed and manufactured, and applied to the vehicle laser methane inspection instrument. The practical application of the gas company showed that:, This equipment greatly improves the efficiency of gas inspection, shortens the cycle of gas inspection, and effectively reduces the occurrence of deflagration accidents
