摘      要：In this work,the wave optics is employed to investigate the Einstein ring of a deformed AdS-Schwarzschild black hole(BH).When the source is fixed on the AdS boundary,one can obtain the corresponding response function generated on the antipodal side of the *** utilizing a virtual optical system equipped with a convex lens,we are able to capture an image of the BH’s holographic Einstein ring on the *** influence of the relevant physical parameters and the observer’s position on the characteristics of the Einstein ring is also investigated,revealing that variations in the observer’s position result in a transition of the displayed image from an axisymmetric ring to an arc,ultimately converging into a solitary point of *** addition,variations in the relevant physical parameters naturally exert influences on the Einstein *** photon ring of the BH was also investigated from a geometric optics perspective,and the numerical results indicate that the incident angle of the photon ring aligns with that of the Einstein *** the context of modified gravity theories,the investigation of Einstein rings formed by deformed AdS-Schwarzschild BH is expected to not only contribute to advancing the development of gravitational theories but also facilitate a more comprehensive understanding of spacetime geometry and the physical properties of BHs,thereby distinguishing them from Schwarzschild BH.
