Seasonal Variation of Laser Induced Fluorescence Spectra in Tree Leaves

Abstract

The seasonal variation of laser-induced fluorescence (LIF) spectra in 28 kinds of trees induced by the UV laser was measured. The spectral data of every tree were shown in the radar graph and classified into five types of variation roughly. In addition, it was found that the feature of the seasonal variation of each tree could be classified quantitatively by analyzing the peak ratio of the spectra. It is thought that monitoring of the change in vegetation may be possible by applying this method to remote-sensing.
