Abstract

We report the hyperspectral imaging system for the measurement of anthocyanin accumulations in ‘bok choy’ grown in the different environmental conditions in the indoor farms. Wavelength bandwidth from 400nm to 700nm that covers chlorophyll A, B, and anthocyanin absorption peaks was three dimensionally (wavelength vs intensity in the area of 100cm2) measured by hyperspectral imaging instrument. Estimated anthocyanin accumulations by hyperspectral imaging technique were compared with those measured by chemical (destructive) analysis. Coinciding results between hyperspectral and destructive analysis suggest that hyperspectral imaging system can be a valuable photonic instrument to replace previously used destructive analysis in agricultural researches.
