Abstract

a invenção descreve um sensor a laser ou um módulo de sensor a laser (100) que usa interferência de automistura para detecção da densidade da partícula, um método relacionado de detecção de densidade da partícula e um produto de programa de computador correspondente. a invenção refere-se, ainda, a dispositivos que compreendem tal sensor a laser ou módulo de sensor a laser. é uma ideia básica da presente invenção detectar partículas por meio de sinal de interferência de automistura e determinar uma densidade da partícula correspondente. além disso, pelo menos um primeiro parâmetro relacionado a pelo menos um componente de velocidade das partículas é determinado a fim de corrigir a densidade da partícula se houver um movimento relativo entre um volume de detecção e as partículas. tal movimento relativo pode, por exemplo, estar relacionado a uma velocidade de um fluido que transporta as partículas (por exemplo, a velocidade do vento). além disso, é possível determinar ao menos um componente de velocidade da velocidade das partículas com base nos sinais de interferência de automistura.
