Compact Chlorophyll Measurement System for Quantitative Analysis of Leaf Photosynthesis in Agriculture

An on-site compact chlorophyll measurement system was developed using a filter-free wavelength sensor to analyze chlorophyll in agriculture quantitatively. The analysis system to detect minute currents with a sensitivity of 1.25 pA changes in filter-free wavelength sensor is designed and fabricated. Currents ratio from filter-free wavelength sensor were used to determine the correlation between chlorophyll content and the chlorophyll a to chlorophyll b ratio. In this result, a compact chlorophyll detection system is expected to analyze plant leaf photosynthesis in agricultural fields.
