To address the problem of optical imaging quality being affected by scattering effect in scattering media,this paper conducts experimental investigation on interpolation processing based polarization imaging denoising method,the purpose of which is to effectively separate the target signal from backscatter noise with the aid of Jaffe imaging model. Firstly,an information interpolation processing and signal extraction model is established based on depolarization property.Secondly,optical path structure of polarization imaging experiment is built for verification.Fat emulsion solution is used to simulate the scattering environment,and orthogonal polarization detection channel images of the scattering scene is obtained under polarized laser illumination conditions.Finally,the obtained polarization images are processed by interpolation and the parameter of signal to noise ratio is used to evaluate the reliability.The experimental results show that the signal to noise ratio values of interpolation processing based polarization imaging method are 112.5, 9.165,13.82,and 11.88,subsequently,which corresponds to concentrations of fat emulsion solutions of 0.1%,0.2%, 0.3%,and0.4%,subsequently.The investigation in this paper can suppress the impact of backscatter noise on the optical imaging process.
