MEMS Near-Infrared Reflectance Absorption Spectrometer for Detection of Composition in Soil

A near infrared absorption spectrometer using MEMS near infrared light source has been assembled. This system was evaluated and found attractive for detection of the composition in soils using a MEMS near infrared light source in the reflectance absorption spectrometer. Analysis and experiments show that, with the traditional laboratory chemical testing technology, the system has advantages of small size, low cost, no pollution, portable, nondestructive, etc, greatly improves the working efficiency of the agricultural science and technology personnel, reduced the working intensity, that do not have the laboratory condition of rural also can be easily for testing.
