The experimental study of weak rough surface characteristic of laser scatter

In this paper, the research meaning and application of polarization characteristic of laser backscattering of the rough surface has been introduced. By designing experimental optical, using incident light of 632.8nm wavelength red light, the experimental study of light scattering characteristics of the existing roughness blocks and other typical rough target surfaces have been done. Analysis results show that scattered light intensity with the measured roughness of the target, the incident angle has a relationship. If the roughness of the measured target is changed, the corresponding scattering intensity and the degree of polarization will change. And if the materials of the measured targets are not the same, the backscatter intensity trends are not identical. The research of light scattering properties of typical rough targets has a positive significance to further study of the target feature.
