Novel Fiber Optic Fluorometer for the Measurement of Alga Concentration

摘要

A novel fluorometer based on fiber optics is briefly introduced for the measurement of alga concentration. Both the exciting light and the fluorescence from alga chlorophyll are transmitted along a fiber cable. By this way, we can get alga concentration by measuring its chlorophyll a fluorescence intensity. The experiment results show that this instrument is characterized by good sensitivity, linearity and accuracy.
