Abstract
Resently a demand to monitor the biological condition of plant has been increased due to the improvement of environmental pollution. Processes such as cytoplasmic streaming, organelle movement, cell growth and division, and biochemical reactions are the functional activities occurring inside of plant leaf. These activities are changed under the influence of environmental stresses. In this study, we proposed to utilize a biospeckle signal to achieve a functional optical coherence tomography (fOCT) to monitor the biological activities of plant. The dynamic speckle pattern obtained when a laser light illuminates leaf is characteristic for living objects and these functional activities and has been called a biospeckle.
