Paper Abstract

An Optical coherence tomography system (OCT system) was developed to measure physiological response inside plant. This system has a unique optical scanner of wide scanning range of 40mm to adapt the OCT measurement to irregular features and many breeds of plant samples. To use in the outdoor field, which plants volunteers, the system should be compact, stable, and have high repetition frequency of measurement. We designed the OCT system with the original optical scanner and optical fiber optics for the purpose. The transmittance and reflectance characteristics of the plant leaves were examined to check the water absorption. The SLD-light of the wavelength of 830nm was selected for the measurement light source. Various kinds of plant samples were measured to evaluate the system performance and its adaptive flexibility. Cell structure of plant surface, its change due to the water content, and growth monitoring of plant tissue were measured. The concrete application was also demonstrated.
