Abstract

The invention discloses an underwater target spectrum polarization multi-dimensional characteristic test simulation device and a measurement method, and belongs to the technical field of optical underwater transmission characteristic measurement and analysis. The simulation device comprises a transmitting system, an underwater environment simulation system, a receiving system, an information processing system, a water injection system and a drainage system. A water tank, a light source and the like are utilized indoors to simulate a complex and changeable underwater environment, a polarized light source and a focal plane camera are combined to determine the optimal imaging angle and distance, then different spectral wavelengths, medium concentrations, water body depths, temperature stratification and salinity stratification are performed, an indoor simulation experiment environment is established for polarization characteristic analysis of an underwater target, environments under various conditions can be flexibly simulated, and the conditions that the imaging effect is poor and unclear are improved. It is proved that the polarization characteristics of the underwater target are different under different conditions, and a theoretical basis and real data support are provided for research on the polarization characteristics of a real underwater environment target.

Description

Technical field [0001] The present invention pertains to underwater optical transmission characteristic measuring technology analysis, especially with regard to multi-dimensional spectral polarization characteristics measuring apparatus and a test method for simulation of underwater targets. Background technique [0002] In recent years, with the development of polarization detection standards of our technical staff to study the polarization properties of different objects has gradually shifted from the landward direction underwater. Underwater goal is to study the polarization properties of the target polarization properties of the future in a very important task. On the other hand, the underwater target characterization may also be important for environmental monitoring of water bodies. 2006 Ralph E.Nothdurft University of Missouri using polarized illumination proactive way to detect turbid medium goals and objectives to improve the analysis of the effectiveness of the visibili...
