소개
An atmospheric visibility sensor is a precision instrument used to measure atmospheric transparency and determine meteorological optical range (MOR). Currently, mainstream visibility sensors operate based on the principle of forward scattering. Simply put, an emitter inside the sensor emits a beam of infrared light into the air, while a receiver, positioned at a specific angle (typically between 33° and 45°) relative to the emitted light, measures the intensity of the scattered light caused by airborne particles (such as fog, haze, rain, or snow). Using a specific mathematical model, the sensor converts the scattered light intensity into a current visibility value.
