Abstract
El escáner divulgado para detectar un tiempo de extinción de la luz emitida por un material luminiscente tiene una unidad de control operable para adaptar la corriente de accionamiento o el valor de la tensión de accionamiento, que energiza su fuente de luz para adaptar en consecuencia la intensidad de la luz de excitación suministrada al material luminiscente de modo que su sensor de luz de alta sensibilidad pueda medir con fiabilidad la luz de luminiscencia emitida en respuesta a la luz de excitación y determinar así con precisión un valor de tiempo de extinción correspondiente.
