Description

technical field [0001] The invention belongs to the technical field of polarization transmission characteristics, in particular to a simulation device for sea fog polarization transmission and a testing method thereof. Background technique [0002] Sea fog When the relative humidity reaches 100% under the conditions of sufficient water vapor, breeze and stable atmosphere, the water vapor in the air will condense into fine water droplets suspended in the air, reducing the visibility at the sea level. This phenomenon is called sea fog. . Sea fog has seriously affected fields such as transportation, sea surface detection, and ocean development. Therefore, the need to study the sea fog environment is more and more urgent. [0003] With the development of modern optical technology, the application of optical detection in marine environment is becoming more and more extensive. However, the outdoor detection takes a long time, the cost is high, the environment is complex and cha...
