Abstract

The paper presents a model sensor system for the simultaneous measurement of fluorescence and transmission for potential application in medical diagnostics. The paper presents results connected with the test substance, fluorescein. The sensor used in the paper includes a neodymium-doped optical fibre to build an asymmetric coupler. The dependence of the intensity of the fluorescence power and transmission on the concentration of fluorescein placed at the end of the system was investigated. Measurements for the presented system were made using UV diode with a wavelength of 415 nm. For the UV source, the effect of fluorescein exposure time on the fluorescence and transmission signals was analysed for different concentrations of fluorescein.
