Introduction
An atmospheric visibility sensor is a precision instrument used to measure atmospheric transparency and determine meteorological optical range (MOR). Currently, mainstream visibility sensors operate based on the principle of forward scattering. Simply put, an emitter inside the sensor emits a beam of infrared light into the air, while a receiver, positioned at a specific angle (typically between 33° and 45°) relative to the emitted light, measures the intensity of the scattered light caused by airborne particles (such as fog, haze, rain, or snow). Using a specific mathematical model, the sensor converts the scattered light intensity into a current visibility value.

principe du capteur de visibilité
- Principe de la diffusion vers l'avant : Estime la visibilité en mesurant l'intensité de la diffusion des faisceaux lumineux par les particules en suspension dans l'air.
- Analyse de l'atténuation de la lumière : Calcule le facteur de transmission atmosphérique sur la base des changements dans l'atténuation de l'intensité lumineuse provoquée par les particules.
- Modèle de réponse à particules multiples : Distingue et compense les caractéristiques de diffusion des particules de tailles et de formes différentes, telles que la fumée, la poussière, la brume, la pluie et la neige, grâce à la différenciation algorithmique.
- Suppression de la lumière ambiante : Élimine les interférences des sources de lumière de fond telles que la lumière du soleil et les phares des véhicules en utilisant des structures d'ombrage optique et des algorithmes de filtrage.
- Compensation de la température et de l'humidité : Corrige automatiquement les variations environnementales affectant la propagation de la lumière afin d'améliorer la précision des calculs de visibilité.
- Filtrage dynamique et traitement de la stabilité : Lisse les signaux de mesure pour éviter les erreurs d'interprétation causées par les impulsions de pluie/neige et les fluctuations transitoires.
