Paper Abstract

This paper describes an efficient method for in-situ measurement of chlorophyll-a concentration in the seawater with fluorescence method and optical fiber techniques. The instrument uses the pulsed xenon lamp as the excited light resources. Both the exciting light and the fluorescence from algae chlorophyll-a are transmitted along two fiber bundles. The fluorescent signal is detected by using the relevant pulsed detecting technology. The minimal detecting concentration of chlorophyll-a in the ocean can reach 1x10-5mg/cm3. The system has advantages of simple structure, passive sensor head and high sensitivity. The experimental results show that this measurement method is realizable.
