Abstract

Fluorescence originating from chlorophyll provides information on the photosynthetic activities of vegetation. We have developed a ground-based remote sensing observation system that enables the stand-off measurements of fluorescence spectrum as well as two-dimensional distribution of fluorescence imagery. The initial laboratory test was conducted by means of the laser induced fluorescence (LIF) method and solar radiation reflected from a cold mirror. Also we describe the field observation based on the direct solar radiation induced fluorescence (SRIF) scheme that has been applied to various vegetation canopies with stand-off distances of 20-30 m.
