Abstract:
The possibility of humidity determination based on the use of spectral distributions in the wavelength range of up to $1 \mu m$ is analyzed. We discuss the use of an imaging hyperspectrometer for precision farming. A field experiment to determine the soil moisture index under the vegetation cover is described. A procedure of precise calibration of the hyperspectrometer based on the use of a tunable laser is described. We show the possibility of the practical determination of humidity based on the use of spectra in the wavelength range of up to $1 \mu m$.
