Abstract

Methods and apparatuses for fundus imaging are presented that use sequential selective illumination patterns to suppress unwanted reflections, scattering and haze from various optical components of a fundus-viewing instrument. This is particularly the case with those unwanted reflections produced by the objective lens contained within said instrument.
