Our spectroscopy and photophysics measurements on solid hydrated uranyl fluorides have shown that luminescence is a powerful method for detecting their presence. We report here the results of those studies and the development of a prototype luminescence imaging system that provides high sensitivity and is optimized for signature detection of hydrated uranyl fluorides. This system provides a high degree of selectivity in that its pulsed excitation source is variable as to wavelength and intensity, and detected luminescence is time-resolved using a spatial light modulator as a fast shutter and wavelength-resolved via bandpass optical filters. The features aid in signature detection of uranyl fluoride hydrates. © 2000 American Institute of Physics.
