Abstract
A gas sensor probe having multipoint reflection rectangular absorption cell, a VCSEL laser emitter and a detection device. The probe comprises: an upper cover plate, the surface of the upper cover plate being provided with gas diffusion holes, and a metal filtering screen being provided above the gas diffusion holes; a lower cover plate located under the upper cover plate and detachably connected to the upper cover plate, and an electric wire through hole being formed in the bottom of the lower cover plate; a light path module located in an internal space defined by the upper cover plate and the lower cover plate and used for modulating the laser emitter and collecting a detection signal; and an electronic processing circuit board located in the internal space defined by the upper cover plate and the lower cover plate, located below the light path module, electrically connected to the light path module, and used for processing the signal generated from the light path module.
