摘要
The present invention discloses a wavelength-modulable spectrum generator as well as a system and method for measuring concentration of a gas component based thereon. The wavelength-modulable spectrum generator includes a filter plate, a to-be-measured gas box and a light intensity receiving plate. A plate surface of the filter plate is encircled with N filter holes, and a filter lens with a specific refractive index is correspondingly fixedly arranged in each filter hole. A light source mounting position is fixed to a side of an in-light surface of the filter plate. After any light source is mounted at the light source mounting position, lights of the light source irradiate the filter lens. A rotation and deflection driving mechanism is connected with an out-light surface of the filter plate and drives the filter plate to rotate or deflect along the axis according to a preset angle.
