Abstract

The speckle pattern fluctuation in the leaf of a plant is investigated by using speckle correlation photography. The speckle correlation method is used to extract the amount of speckle pattern fluctuations. The speckle pattern fluctuations are related to the water content of the sap, which is in the veinous structure of a leaf. The speed of sap flow in veins is obtained by this method.
