Abstract
"UM ESPECTRÈMETRO INCORPORANDO FILTRAGEM COMBINADA DE SINAL". A invenção refere-se a um sistema óptico para realizar uma análise espectral de amostras de teste. O sistema óptico compreende uma fonte de energia fotónica, um sistema de processamento de emissão óptico, um sistema de processamento óptico de luz recebida, um detector óptico e um sistema de processamento digital. A fonte de energia fotónica emite radiação eletromagnética e é controlada por um sistema de processamento de sinal digital. O sistema de processamento de emissão óptica recebe radiação eletromagnética da fonte de energia fotónica e transmite um ou mais comprimentos de onda de iluminação para uma amostra de teste, em que o sistema de processamento de emissão óptica é controlado pelo dispositivo de processamento de sinal digital. O sistema de processamento óptico de luz recebida coleta e isola um ou mais comprimentos de onda de radiação eletromagnética recebida da amostra de teste e transmite um ou mais comprimentos de onda isolados de radiação eletromagnética recebida para um detector óptico. O sistema de processamento óptico de luz recebida é também controlado pelo sistema de processamento de sinal digital. O detector óptico sente e converte um ou mais comprimentos de onda isolados de radiação eletromagnética recebida em um sinal elétrico que é transmitido para sistema de processamento de sinal digital. O sistema de processamento de sinal digital realiza filtragem combinada do sinal elétrico recebido do detector óptico e adicionalmente controla a funcionalidade da fonte de energia fotónica, o sistema de processamento de emissão óptica e o sistema de processamento óptico de luz recebida.
