Development of Portable Fourier Spectrometer for Rapid Analysis of Chemicals Used for Crops Treatment in Agriculture

The article discusses a static Fourier - spectrometer of the near ultraviolet (UV) and range intended for the detection of substances on various underlying surfaces. The necessity of developing a statistical Fourier spectrometer for solving various tasks, including for controlling the amount of chemical compounds in agriculture, is substantiated. The Fourier spectrometer was tested for various substances. The coincidence of the concentrations of the values determined by the Fourier spectrometer and measurements by other methods was established. Measurements of the content of chemicals in the soil in the fields in the express mode were carried out. The measurement results are presented, and their analysis is performed. A comparison between the developed Fourier spectrometer and an industrial dynamic Fourier spectrometer is presented.
