Abstract

The embodiment of the invention provides an optical system, a gas cloud imaging camera and a gas detection device, which can be applied to the field of gas detection, and the optical system comprises an objective lens, a collimating lens, an m * n lens array, an m * n optical filter array and an m * n detector array which are arranged in sequence. The objective lens is used for imaging a scene of a target area, the target area comprises at least one pollutant gas, the collimating lens is used for processing imaging light after imaging of the objective lens to obtain a collimated light beam, the m * n lens array is used for aperture division multiplexing, the m * n optical filter array is used for filtering light, and the m * n detector array is used for signal conversion. The final digital signal information of the m * n areas is obtained, and the digital signals of the m * n areas are used for reflecting the types of the pollutant gas and / or the amount of the gas substance. According to the optical system provided by the invention, the mode of combining the m * n optical filter array and the m * n lens array is adopted, the types of gas detected on line (depending on the number of m * n) can be increased, and the detector array can realize quantitative analysis.
