Abstract

En la presente se describen sistemas y métodos que mitigan el cegamiento del fotodiodo de avalancha (APD) y permiten precisión mejorada en la detección de una señal de luz multiretorno. Un punto ciego puede ocurrir debido a la saturación de un APD primario. Los sistemas y métodos incluyen la incorporación de un APD redundante y la utilización de la diversidad de tiempo y la diversidad de espacio. La detección por medio de los APDs se activa mediante una señal de derivación. El APD redundante recibe una señal derivada retrasada en tiempo comparada con el APD primario. Adicionalmente, el APD redundante se coloca fuera del plano focal principal con el fin de atenuar una salida del APD redundante. Con atenuación, el APD redundante puede no saturar y puede tener una detección exitosa durante el punto ciego del APD primario. Las modalidades pueden incluir APDs primarios múltiples y APDs secundarios múltiples.
