Abstract

Dispositivo para detectar partículas luminiscentes reactivas incorporadas en un sustrato o superficie que comprende: un iluminador infrarrojo o ultravioleta para iluminar las partículas luminiscentes; un sensor de fotodiodo de infrarrojo cercano para captar una respuesta en el infrarrojo cercano de las partículas luminiscentes iluminadas; una cámara oscura para colocar sobre el sustrato o la superficie, dentro de la cual están montados el iluminador y el sensor de fotodiodo; un amplificador logarítmico para amplificar y linealizar una señal de respuesta captada por el sensor de fotodiodo; un procesador de datos electrónico configurado para detectar las partículas luminiscentes reactivas, llevando a cabo las etapas siguientes: iluminar el sustrato o la superficie con el iluminador; adquirir la señal linealizada y amplificada captada por el sensor de fotodiodo; detectar la presencia de partículas luminiscentes en el sustrato o la superficie a partir del decaimiento linealizado de la señal adquirida. Comprende un sensor de fotodiodo de infrarrojo cercano adicional, un amplificador logarítmico adicional y un diferenciador para obtener una diferencia entre señales amplificadas recibidas por cada sensor de fotodiodo.
