Abstract

Based on analyzing the infrared laser’s transmitting characteristic in the seawater, the concept about the red tide infrared scattering coefficient is introduced. By analyzing the relationship between the red tide infrared scattering coefficient and the red tide’s density, we bring forward a new method of monitoring the red tide based on detecting the red tide infrared scattering coefficient. According to Mie scattering theory, the scattering efficiency factor and the scattering phase function of the red tide particles in the ocean are simulated and calculated. The result proves that, as the radiuses of the red tide particles increase, the scattering efficiency factor oscillates, and the swing decreases gradually, and then approaches to 2. From the results of the scattering phase function, it can find that the scattering of the red tide particles is mainly a forward scattering for the infrared laser. Therefore, by analyzing the scattering efficiency factor and the scattering phase function of the red tide particles in the ocean, it can prove the feasibility of this red tide monitoring method in theory.
