The imaging LIDAR is one of the methods for measuring the revitalization degree of some kinds of plants. The technique was based on the LIF, Laser-induced Fluorescence method and LIDAR, light detection and ranging. In the LIDAR that uses the LIF method, the surface of plant leaves is irradiated by laser beam, for example, the second harmonic generation of the Nd: YAG laser, 532nm, and the fluorescence that occurs at that time is observed. This fluorescence has two spectral peaks in the wavelengths of 740nm and 685nm. The ratio of the optical strength of 740nm to that of 685nm is correlated very well with the revitalization degree of the plant. Therefore, the revitalization degree of the plant can be examined by measuring the ratios. The revitalization degrees of leaves of six kinds of plants were measured by using this method. Vivid and withered leaves of the six plants were selected as specimens. As result, it is found that there is a criterion that the ratio of the optical strength of 740nm to that of 685nm has a critical value and the plant is vivid if the ratio is greater than unity and withered if the ratio is less than unity. It was reconfirmed that the technique is useful to remotely measure plant activity.
