The imaging LIDAR is one of the methods for measuring the revitalization degree pf some kind of plant. The technique is based on the LIF, Laser-induced Fluorescence method and LIDER, light detection and ranging. It is known that the chlorophyll fluorescence shows a linear correlation to the chlorophyll concentration. Applying this methods, we investigated the influence acid rain to a vegetable. The acidity of the simulated acid rain water were pH5.5, pH5.0, pH4.5, pH4.0, pH3.5, pH3.0, and pH 2.5. These eight kinds of waters of the simulated acid rain including city water were added to each pot of spinach. The waters of 15cc were added everyday in a weekday during three weeks. The simulated acid rain with typical pH valued did not make all of these bunches of spinach wither after three weeks. For this time, the imaging LIDER demonstrate more definitely the activity of each spinach than a digital camera observation.
