“…a set of short-wave infrared hyperspectral imaging spectrometer using InGa As array detector and DMD device [22] . In 2011, Professor Wen Zhiyu's team from Chongqing University developed the near infrared spectrometer based on DMD, designed and optimized the light source and spectral imaging system, corrected the coding error, calibrated the wavelength, and wrote the relevant application software [23][24] . The test results of the instrument showed that: The wavelength range is 1000-1780nm, and the spectral resolution is less than 20nm, which realizes the aberration correction and the miniaturization of the optical system.…”

Near infrared spectroscopy has been applied to qualitative and quantitative analysis in many fields due to its advantages of fast measurement speed, high accuracy and continuous measurement. Digital micromirror array is an electronic input and output optical mems, semiconductor manufacturing technology combined with the height of the integrated circuit manufacturing technology, make its in resolution, contrast, brightness, grayscale, color fidelity and main performance parameters, such as response time reached the high level, high reliability, fast response speed. In recent years, near-infrared spectroscopy based on wavelength grating and modulation characteristics of DMD has become a research hotspot. This system has the advantages of high signal-to-noise ratio, excellent comprehensive performance and low cost, and has attracted much attention in many application fields. In this paper, the principle, development history, application status and development direction of near infrared spectroscopy based on DMD are reviewed, which provides a basis for the related research of DMD near infrared spectroscopy analysis technology.
