Optical fiber sensors for monitoring agricultural drone spraying operations

spraying

Spraying is a fundamental agricultural operation, used for the dispersion of both pesticides and fertilisers over trees and crops, directly affecting the volume and quality of agricultural yield; however, spraying is subjected to limitations with respect to safety regulations, water consumption and droplet cloud drift. An emerging agricultural trend is referring to drone spraying operations, offering prominent and unique advantages such as speed of operation, applicability to almost every type of ground and crops, and significant saving in water and pesticides/fertilisers.

HyperSlit is a compact hyperspectral sensor for small drone (DJI Mavic) in the ultraviolet to near-infrared (UV/VIS/NIR) range (190–810 nm). This ultralight system weighs a ready-to-fly 340 gr. The spectral resolution of collected data by HyperSlit is 0.5 nm which allows collecting high-resolution (1024 spectral bands) crop spectral resolution.
