Abstract

La presente especificación describe un detector de radiación multi-energía mejorado; en una modalidad, la señal generada por el medio de detección es convertida a forma digital directamente en el punto de la recolección de señal; esto evita la necesidad de amplificadores de ancho de banda alto de potencia intensa y convertidores análogo-a-digital, ya que integra el dispositivo de detección y el procesamiento de señal en el mismo sustrato de silicio para reducir el número de componentes en el sistema; en una modalidad, un diodo de avalancha de fotón único (SPAD) está acoplado directamente a un detector de umbral para lograr un detector de bajo ruido y baja potencia intrínsecamente.
