We show that the spherical photon orbits with impact parameters in a finite range converge on the event horizon. Furthermore, we demonstrate that the Weyl curvature near the horizon does not generate the shear of a congruence of such light rays. Because of this property, a series of images produced by the light orbiting around a near-extremal Kerr black hole several times can be observable.","subitem_description_language":"en","subitem_description_type":"Abstract"},{"subitem_description":"This work was supported by Grant-in-Aid for Early-Career Scientists [JSPS KAKENHI Grant No. JP19K14715] (T.
