Abstract

A process and system including a detector having a photosensor therein that outputs a signal and a plurality of after-pulse detector devices independently connected to the photosensor via respective pathways. The after-pulse detector devices each detecting an after-pulse in the signal, where the after-pulse represents an after-event in the photosensor triggered from a previous photon generating event. The system further includes a processing device that receives an indication of the detection of the after-pulse from each of the plurality of after-pulse detector devices and determines a relative delay between the respective pathways based on timing the received indications, and includes a memory that stores the relative delay in association with an identification of the corresponding after-pulse detector devices.

First claim

The invention claimed is:

1. A timing delay detection system, comprising:
a detector including a photosensor configured to output a signal;
a plurality of after-pulse detector devices independently connected to the photosensor via respective electronic pathways, the after-pulse detector devices each configured to detect an after-pulse in the output signal and output an indication when the after-pulse is detected, the after-pulse representing an after-event in the photosensor tri…
