The portable instrumental prototype is composed of: a) UV-VIS-NIR Reflectance unit; b) UV-VIS-NIR steady-state fluorescence unit; c) UV-Vis fluorescence time-decay unit. The reflectance unit is composed of a compact Deuterium-Halogen lamp coupled with high sensitive CCD spectrometers working in the UV-VIS-NIR which allow reflectance spectra between 200-1600 nm range to be collected. The steady-state fluorescence unit is composed of pulsed diode lasers and LEDs at 375, 450 and 630 nm coupled with highly sensitive CCD spectrometers working in the UV-VIS-NIR which allow steady-state fluorescence measurements between 200-1600 nm range to be collected. The fluorescence time-decay unit is composed of pulsed diode lasers and LEDs at 375, 450 and 630 nm in the ns-ms lifetime range coupled with high sensitive photocathode working in the 350-850 spectral region which allow time-resolved fluorescence experiments to be performed. A dedicated fibre optic system allows measurements on any surface to be done. The size of the whole probe is less than 2 mm2. The analysed object can be in whatever position and a free area of about 2x2 meters is needed for the positioning of the instrumentation in the proximity of the object to be investigated. Low intensity of illumination, despite not mandatory, allows a better result to be obtained.
