Abstract: A calculation method for fractal dimensions of shale pores includes steps as follows. S1: multiple shale samples from a target stratum of a study area are obtained, parameter values of geological parameters of each of the multiple shale samples are obtained, followed by dividing the multiple shale samples into target shale samples and experimental shale samples. S2: PCA is performed on the parameter values to obtain principal components representing a variation of the geological parameters. fractal dimensions are calculated based on an existing fractal dimension calculation method. S3: the principal components are used as independent variables and the fractal dimensions are used as dependent variables, followed by performing regression analysis to obtain a quantitative calculation model. S4: the fractal dimensions of the target shale sample are calculated according to the parameter values and the quantitative calculation model for the fractal dimension based on the parameter values.

Abstract: A reflective polarization volume hologram (rPVH) layer in combination with a quarter wave plate (QWP) is used to provide optical power and to correct chromatic aberration in an optical assembly of an augmented and/or virtual reality (AR/VR) near-eye display device. The rPVH layer introduces more degrees of freedom to further improve contrast of the optical system and reduces a thickness/weight of the optical assembly. The rPVH layer is flexible, thus, allowing curved lamination on an optical lens. Moreover, the rPVH layer is sensitive to circular polarization. Thus, it can filter right-handed circular polarization (RHCP) or left-handed circular polarization (LHCP), without a need for the QWP.
