Abstract: An assessment assembly (10) for assessing a fundus imaging system (12) includes at least one, curved, flexible resolution test chart (40). Each of the resolution test charts (40) can include a chart body (342), and a plurality of spaced apart chart features (344). Moreover, each of the resolution test charts (40) can be fixedly coupled to an artificial retina region (36) of an artificial eye (14). The artificial retina region (36) can be shaped and sized similar to a retina region (19E) of a human eye (19), and the artificial retina region (36) can have scattering and depolarization properties that are similar to the scattering and depolarization properties of the retina region (19E) of the human eye (19). The fundus imaging system (12) can capture one or more images (20) of the resolution test charts (40) that are evaluated to determine a resolution of the fundus imaging system (12).
