摘要

We present a conceptual design of a multidimensional fluorometer, where a set of individually controlled laser diodes used as excitation light sources enables the user to obtain 3D spectra, i.e., excitation-emission matrices (EEMs), in a single measurement as well as acquire multidimensional spectra by scanning excitation and emission wavelengths and the power density and frequency modulation of excitation light. The performance of our fluorometer prototype is evaluated by authenticating protected objects marked with upconverting security markers. A method based on the analysis of EEMs representing security markers for authenticating objects is proposed to avoid authentication errors and to improve the speed of information processing by introducing digitized EEMs, basis EEMs, and basis markers.
