Abstract:

An online in situ fiber optic sensor used for detecting the chlorophyll-a content was designed by fluorescence detection technology. The sensor was based on optical fiber transmission and fluorescence analysis method, which could be used to capture, transmit and analyze the fluorescence signal to achieve the goal of online rapid detection of chlorophyll-a. Experimental results show that the response value of the sensor has a good linear relation with the concentration of chlorophyll-a. And the sensor has the advantage of stable performance,  small size, and fast transmission speed, etc. Therefore, the sensor has preliminarily obtained the online in situ detection capability of chlorophyll-a content in seawater.

Key words: sensor, chlorophyll-a, fluorescence method, ocean pollution
