Outline of Final Research Achievements

We developed a plant monitoring system based on optical technique which could cover a wide spectrum region from X-ray to Teraherz, named a ultra-wide-band spectral(UWBS) monitoring system. A mid-infrared　spectrum　(MIFS) monitoring system was newly developed and built into the UWBS monitoring system. The MIFS monitoring system was consisted of a ceramic-heater as an MIF source, a confocal imaging system and a HgCdTe detector with a peltier-cooled spatial filter.
System performance was investigated by monitoring spectrum of some plant leaves (REDROBINI, AOKI, KUNUGI and others). Plant physical information as leaf inside structure in X-ray and physiological information such as photochemical reflectance in visible, water content in near-infrared and Teraherz, and leaf-surface temperature in thermal infrared.
Through these experiments, technological basics of a plant health diagnosis was established.
