- Abstract
A sensitive in-situ oil measurement scheme in seawater, consisting of the optical system, the photoelectric detection circuit system, the data acquisition and control system, is proposed to facilitate the measurement of the oil in seawater. It has long been supposed that there must be a linear relation between fluorescence intensity and concentration of oil. Now, it is difficult to detect the faint fluorescence signal which submerged into the strong noise by using traditional methods. To deal with this drawback, we devise a detection method of sampling integral to facilitate the extraction of the fluorescence signal from the background signal in the current work. The proposed scheme which comprise of the xenon flash lamp trigger to excite the fluorescent signal, the narrowband filter to filter out the additional environment light and the high sensitivity photomultiplier tubes (PMT) as detector to perceive of the faint fluorescent signal. In particular, the feeble fluorescence signal is well detected through the preamplifier circuit, filter circuit and an integrating circuit. The obtained results indicate that the proposed detection system is much superior to the traditional system in the detection of oil in seawater with substantially reduced system and environment noise discrepancies. This permits the oil detection system to be capable of acquiring faint fluorescent signal which shielded by vast powerful noise.
