Abstract

The present invention relates to a system (100) and method to extract phase shift of fluorescence signal. The system (100) comprises of a Frequency Generation Unit or FGU (10), a light-emitting diode or LED (20), a sensor element (30), a phase shifter (40), a photo detector (50), a radio frequency (RF) switch (60), a low pass filter (LPF) (70), a trans-impedance amplifier (TIA) (80), and a digital processor (not shown). The photo detector (50) is configured to convert a fluorescence signal from the sensor element (30) into an electrical current signal and also, to multiply the fluorescence signal with either the quadrature signal or the known in-phase signal as selected by the RF switch (60).
