Device for testing polarization characteristic of laser in non-uniform haze medium

The invention discloses a device for testing the polarization characteristic of laser in a non-uniform haze medium, and belongs to the technical field of polarization transmission testing. The device comprises a laser emitting system, a non-uniform haze simulation device, a smog generating system, a receiving system and a fog discharging system. The interior of a box body of the non-uniform haze simulation device is divided into more than three layers, and a spray tower with an adjustable spire angle and a gas circulation system are fixedly mounted in each layer. According to the invention, the generation of the non-uniform haze environment can be independently completed, haze gas is simulated by adopting a method of burning a smoke cake, the non-uniform haze simulation device with more than three layers is designed, and a layered gas environment with the concentration from low to high from top to bottom, namely the non-uniform haze simulation environment, can be generated in cooperation with the smog generat
