Abstract
A method and system for characterizing and quantifying various error and calibration components of signals associated with photo-detectors. By varying the detector operational parameters such as input light intensity and integration times, measured signals can be analyzed to separate out and quantify various components of the measured signals. The various components thus determined may be categorized according to their dependencies on the operational parameters. Such component characterization allows better understanding of the detector system and ways in which such system can be improved so as to yield an improved measurement result for which the detector is being utilized.
