Abstract: Measuring plants’ sensitivity to environmental stresses can help us understand the environmental and ecological conditions in the area. Optical Coherence Tomography (OCT) can visualize and evaluate the internal plant structure quantitatively. In this study, as a preliminary step to assess the atmospheric environment by field measurements of plants using OCT, the influence of the ozone gas and the effect of the plant-clearing agent in OCT measurement were evaluated. The plant-clearing agent makes the internal refractive index uniform and allows evaluation of the extinction coefficient from the leaf’s full cross-section image. The results showed an increase in the extinction coefficient and its palisade thickness. The extinction coefficient significantly changed between before and after exposure to ozone gas to 16.9 ± 6.2 [/mm] from 12.6 ± 3.42 [/mm]. This result indicates that OCT can measure plant responses to environmental changes quantitatively. Field measurement of plants by OCT w ill allow environmental assessment anywhere in a short time.
