摘要	As a new type of spatial light modulator, Digital Micromirror Device (DMD) has the advantages of high resolution, low production cost and high processing efficiency. It is very flexible to use, so the laboratory built a near infrared spectrometer based on DMD. First, the basic working principle of DMD near-infrared spectrometer was introduced. Secondly, the wavelength of spectrometer was calibrated, a method based on the correlation coefficient of the same sample absorbance curve was proposed to normalize the inter-wavelength difference, so that the inter-station difference of the wavelength was theoretically less than 0.1 nm, which meet the requirements when the model was transferred. The selection criteria of different coding templates for DMD near-infrared spectrometer were obtained by comparing the noise and signal-to-noise ratio test under strong light and weak light conditions: the scanning method was better than the Hadamard method under strong light conditions, the opposite in weak light. Finally, the actual sample gasoline and diesel were tested by the spectrometer, and the test results showed that the spectrometer performance was stable. The near-infrared spectrometer based on DMD has a detection wavelength range of 1 330 to 2 500 nm, absorbance deviation is less than 0.000 4 AU. 2019, Editorial Board of Journal of Infrared and Laser Engineering.
