Abstract

"MéTODO E APARELHO PARA ESPECTROSCOPIA óTICA". A presente invenção fornece um método para espectroscopia ótica, em particular espectroscopia Raman, para realizar análise de sangue invasiva e não invasiva. O componente de fluorescência de radiação de retorno, que é recebido a partir de um volume de detecção é eliminado, o que é possibilitado por meio da utilização de uma fonte de luz de excitação pulsada. O comprimento do pulso é substancialmente mais curto do que o tempo de vida da fluorescência. Daí, a eliminação do componente de fluorescência pode ser realizada por controle de tempo, ou por meio de outro dispositivo eletrónico ou ótico.
