Studies on Using Optical Sensors in Agricultural Production

The optical sensors for assessing the condition of crops are based on the analysis of the wavelength of the light reflected by the vegetal mass, i.e. the measurement of the wavelength type and intensity of light reflected back to the sensors. In general, optical sensors are based on the ability of vegetation to reflect incident electromagnetic radiation, which allows for correlation between the qualitative and quantitative data characterizing agricultural crops. Sensors for measuring crop reflectance can be graded by platform, such as: aerial or spacecraft (satellites, aircraft, unmanned aerial vehicles, balloons), field means (hand-held sensors, sensors mounted on agricultural machinery).
