System and method for digital parallel frequency fluorometry |
摘要 |
A system and method is provided for improved fluorescence decay time measurement. A digital heterodyning technique is disclosed in which a photon detector is sampled at a rate slightly faster than a digitally pulsed excitation signal. A resulting cross correlation frequency is low enough to be read by inexpensive electronics such as by a field programmable gate array. Phase information in the signal provides correlation with corresponding photon detections. |
