Abstract

The invention provides a multi-channel seawater transparency measuring device which comprises a sealed transparency measuring disk, an optical measuring device and an optical communication device, wherein the optical measuring device is embedded in the center of the transparency measuring disk, and the measuring plane of the optical measuring device is positioned on the front surface of the transparency measuring disk; the optical measuring device comprises an upper shell and a lower shell which are in hollow connection with each other, and protective glass is arranged in the hollow parts of the two shells; one side of the protective glass is in contact with the upper shell through a rubber isolation ring, and the other side of the protective glass is in contact with a plurality of optical filters with different wave bands through rubber isolation rings; a photodiode penetrating through the lower shell is arranged at the bottom of each optical filter to form a channel, and the multiple optical filters with different wave bands and the corresponding photodiodes form a plurality of different channels. By adopting a multi-channel and narrow-band measurement mode, the multi-channel seawater transparency measuring device can obtain radiation count values of different channels in different depths of seawater and further obtains the seawater transparency and extinction coefficient profiles of different channels.

Description

technical field [0001] The invention is a device and method for measuring seawater transparency based on optical principles, which are mainly used in the field of ocean detection. Background technique [0002] Seawater transparency refers to the degree of turbidity of seawater, which reflects the extinction characteristics of seawater. The horizontal and vertical distribution of seawater transparency is an important factor affecting the distance and effect of underwater communication, underwater optical imaging, and underwater laser detection. Real-time and accurate seawater transparency profile data are required to carry out military activities such as underwater communication to submarines, submarine submersion and anti-submarine, mine laying and mine detection, and seabed surveying and mapping. The naval hydrographic support capability is of great significance. [0003] Currently, seawater transparency measurement methods include lead type method, cross method, and Seph...
