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