Abstract

Due to the complexity and variability of the marine environment, the weak useful signals of the measured marine optical instruments often have strong background noise and nonlinear characteristics, which seriously affect the detection accuracy of the weak useful signals. In this paper, the interference of background optical noise in in-situ optical instruments is studied. From the perspective of optical signals received by the instrument detection system, the types of optical signals received are analyzed, and the energy level, spectral characteristics, and spectral characteristics of interference signals and useful signals are analyzed. The noise removal scheme is discussed, which provides the theoretical basis and design basis for the in-situ optical sensor design.
