Spectral signatures identifying Instrument on Spectroscopic Measurement technique for Water quality monitoring

摘要

Spectral measurement is an important technology for measuring algal-chlorophyll in surface water. This paper provides a possibility of spectral signatures in the visible and near infrared, associated with experiments could be conduct to use proposed devise for outdoors in water environments. The overall objective of this study was to use development of micro controller based Spectrometer for finding possible spectral regions in which chlorophyll-a (Chl-a) could be identified so as to assist the assessment and monitoring of water quality spectrometric method. The main target is to develop very low cost effective with mobility and to get current data by accessing remotely. This study based on the application of linear regression analysis between the mean reflectance values (proposed Micro controlled visible Spectrometer-MVSM－C10988MA-01) across the spectrum and the concentrations of chlorophyll-a (μg/L) acquired simultaneously in situ measurement on the same day and time in the Ibaraki University Test Pond in Japan.
