Abstract

Aiming at rapid measurement of four chloroplast pigment of plant leaf

a rapid measuring instrument is designed based on photoelectric nondestructive technique and near infrared（ IR） spectroscopy. The instrument uses ATmega 128 A microprocessor as core

use 8 LED array and rotary measuring mode and use OPT101 photoelectric sensor for photoelectric conversion and send detecting result to microprocessor for processing and preservation

this instrument can measure four kinds of chloroplast pigment that is chlorophyll a

chlorophyll b

lutein and carotenoids. Experimental results illustrate that measurement results of the instrument and Uni Spec-SC Spectral Analysis System spectrometer are consistent

measurement value can accurately characterize contents of the four kinds of pigments with advantages of convenient to carry

simple structure and high reliability of measurement results

and it has certain practical value for agriculture and forestry research.
