System and method to unpile overlapping pulses

Abstract

A system includes a scintillator to receive radiation and to generate a plurality of light photons in response to reception of the radiation, a light sensor to receive light photons and to generate an electrical signal in response to reception of the light photon, and a processing unit. The processing unit is to receive the electrical signal from the light sensor, determine a first integral over a first number of samples of the electrical signal, determine an estimated energy of a first pulse based on the first integral, where the electrical signal includes the first pulse and a second pulse, where a portion of the second pulse overlaps a portion of the first pulse, determine a second integral over a second number of samples of the electrical signal, determine a second estimated energy of the first pulse over the second number of samples, determine a residual short integral of the second pulse based on the second integral and the second estimated energy, and determine an estimated energy of the second pulse based on the residual short integral of the second pulse.
