Abstract

"SISTEMAS E MéTODOS PARA DETERMINAR ESPECTROS USANDO ALGORITMOS DE INFERêNCIA DE LóGICA POLIVALENTE COM MEDIçõES A PARTIR DE SENSOR DE LED COLORIDO". A invenção refere-se a um espectrofotómetro à base de LED que usa um algoritmo de reconstrução, com base em informações espectrais de uma fonte de iluminação e um espectrofotómetro de referência, para converter medições iluminantes múltiplas integradas de um sensor colorido povoado totalmente iluminante em uma curva espectral totalmente povoada usando um banco de dados de referência. Um modelo não linear, tal como um sistema de inferência de lógica polivalente (FIS) é usado para reconstruir os espectros.
