SYSTEMS AND METHODS FOR DISTINGUISHING OPTICAL SIGNALS OF DIFFERENT MODULATION FREQUENCIES IN AN OPTICAL SIGNAL DETECTOR

摘要

Systems and method for detecting optical signals, and for discriminating optical signals emitted by an emission moiety that is excited by an associated excitation signal from background signals and other optical noise, employing digital techniques for determining the portion of a detected optical signal having a modulation frequency corresponding to a modulation of the associated excitation signal.
