FIELD: physics, control.
SUBSTANCE: invention is intended for monitoring a plurality of discrete fluorescence signals, particularly for DNA sequencing using fluorescently labelled nucleotides. The detector (118) comprises a plurality of pixels (130) for individually detecting said fluorescence signals from the plurality of fluorescent signal sources (104), wherein each pixel (130) comprises a predetermined number of at least two detection elements (D1, Dn) for detecting a received fluorescent signal and for generating detection signals, as well as a signal conversion circuit (140) for receiving said detection signals from said at least two detection elements (D1, Dn) and for generating a pixel output signal indicating which of said at least two detection elements (D1, Dn) generated the strongest detection signal.
EFFECT: monitoring a plurality of discrete fluorescence signals.
