Testing device for spectral polarization BRDF/BTDF of sea surface transparent floating object

The invention relates to a device and a method for testing spectral polarization BRDF/BTDF of a sea surface transparent floater, which belong to the technical field of BRDF and BTDF measurement and comprise a marine environment simulation system, a support system, a guide rail system, a polarization emission system, a polarization BRDF receiving system, a polarization BTDF receiving system and a computer system. The device is suitable for measuring sea surface floaters (oil spilling, red tide and transparent/semitransparent targets), performing overwater, water surface and underwater omnibearing detection on the targets, obtaining polarization information of the upper surfaces, in contact with the air, of the targets and the lower surfaces, in contact with the water surface, of the targets, simultaneously measuring BRDF and BTDF characteristics of the targets according to the obtained information, mastering reflection and transmission characteristics of the targets, and determining the target quality.
