Abstract
Official abstract text for this publication.
A fluorescence based sensor system that provides improved signal-to-noise over prior systems is provided. The system includes a fluorescence based sensing medium that is contained a recessed cavity with reflective sides that allow for more uniform excitation of the fluorescence based sensing medium by the excitation light.
First claim
Opening claim text (preview).
What is claimed is: 1. A fluorescence based sensor for measuring at least one parameter of a medium, comprising: a fluorescence based sensing medium having a top surface, a bottom surface and at least one side surface, wherein the fluorescence based sensing medium exhibits fluorescence properties that vary when the fluorescence based sensing medium comes into contact with the at least one parameter being measured; a reflective surface adjacent to the at least one side surface of…
