Laser-based dew detection
Résumé
Agriculture is in need for new sustainable solutions in order to reduce their phytosanitary products utilization. To this end, the early detection of the necessary conditions for disease development is a key to their reduction. Combined with a laser source, such a tool can do fast measurements on a field scale and, by doing so, help farmers in containing diseases. Thus, a laser-based sensor has been developed for wetting monitoring. Using the Heiligenschein phenomenon, it has been proved effective on both hydrophilic and hydrophobic surfaces in controlled conditions
