Introdução
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.

princípio do sensor de visibilidade
- Princípio de dispersão para a frente: Estima a visibilidade através da medição da intensidade de dispersão dos feixes de luz pelas partículas em suspensão no ar.
- Análise da atenuação da luz: Calcula a transmitância atmosférica com base em alterações na atenuação da intensidade da luz causadas por partículas.
- Modelo de resposta de múltiplas partículas: Distingue e compensa as caraterísticas de dispersão de partículas com tamanhos e formas variáveis - como fumo, poeira, neblina, chuva e neve - através de diferenciação algorítmica.
- Supressão da luz ambiente: Elimina a interferência de fontes de luz de fundo, como a luz solar e os faróis dos veículos, utilizando estruturas de sombreamento ótico e algoritmos de filtragem.
- Compensação de temperatura e humidade: Corrige automaticamente as variações ambientais que afectam a propagação da luz para melhorar a precisão do cálculo da visibilidade.
- Filtragem dinâmica e processamento de estabilidade: Suaviza os sinais de medição para evitar erros de interpretação causados por impulsos de chuva/neve e flutuações transitórias.
