SYSTEM AND METHOD OF EXTENDING THE LINEAR DYNAMIC RANGE OF EVENT COUNTING

Title:

SYSTEM AND METHOD OF EXTENDING THE LINEAR DYNAMIC RANGE OF EVENT COUNTING

Document Type and Number:

WIPO Patent Application WO/2012/047627

Kind Code:

A3

Abstract:

A method and apparatus for photon, ion or particle counting described that provides seven orders of magnitude of linear dynamic range (LDR) for a single detector. By explicitly considering the log-normal probability distribution in voltage transients as a function of the number of photons, ions or particles present, the binomial distribution of observed counts for a given threshold, the mean number of photons, ions or particles can be determined well beyond the conventional limit.
