Abstract
A compact fluorosensor using three different ultraviolet light-emission diodes as excitation sources for fiber-optic recording of fluorescence
10 spectra from samples is described. A compact integrated spectrometer with linear array wavelength recording is used, yielding a spectral resolution
11 of about 8 nm. In two system implementations ultraviolet light-emitting diodes at 300, 340 and 395 nm, or at 360, 385 and 410 nm were used as
12 excitation sources with typical emission halfwidths of 12 nm, each combined with a matching long-path colored-glass filter automatically brought
13 into the fluorescence light flow for suppression of reflected light. Spectra from measurements on vegetation, human skin tumors and a rare-earth
14 ion-based thermographic phosphor were recorded to illustrate the system performance.
