| Outline of Final Research Achievements |
A stand-off system has been developed for observing solar-induced vegetation fluorescence on the canopy level. The system collects optical signals using a telescope, leading to the spectral measurement using a CCD spectrometer, as well as the two-dimensional measurement of the fluorescence intensity distribution by means of a cooled CCD camera. The spectrum of whiteboard taken simultaneously with that of vegetation canopy is used as a reference to extract the fluorescence intensity. The system has been tested both in laboratory and field experiments conducted at rice,soybean field and forest sites in Kyoto. It is found that the present approach based on the exact spectral shapes is useful for extracting weak fluorescence signals even under daylight conditions for rice, soybean and forest canopies.
