Patent EP-0402030-A2 (EP)
Inventor: WILLIAMS RICHARD E C O MINNESO
IPC: G01N21/64
Filed: 1990-05-30
Abstract: An apparatus for detecting the fluorescence of a luminescent material (12). Photo-diodes (22,24) receiving the visible fluorescence from a target luminescent material and a luminescent reference (18) are coupled "back-to-back" resulting in a single-channel detector inherently balanced and insensitive to variations in the excitation stimulus. The photo-diode output is sent through a second harmonic amplifier (34) making available a phase detection of the fluorescence instead of an amplitude detection. The phase of the signal is compared with a known phase from the excitation power source. By adding signals that either reinforce or oppose, the phase information is converted back to amplitude information at a voltage level that can be easily detected. The detected amplitude is compared against the amplitude of the excitation stimulus to account for amplitude variations in such stimulus. The compared output then triggers an indicator producing an indication of the amount of fluorescence of the target luminescent material.
