(54) A FOURIER-DOMAIN OCT APPARATUS FOR OPTORETINOGRAPHY


(57) A Fourier-domain OCT apparatus for acquiring optoretinography data, comprising: a fixation target which fixes a gaze direction of an eye; an optical system which applies an optical stimulus which is confined to a portion of a retina of the eye whose location is controllable; an OCT imaging system which acquires OCT data from the retina; and a controller which: acquires a target location on the retina; uses the target location to control the optical system, while a position of the fixation target relative to the eye remains fixed, to apply the optical stimulus to a first portion of the retina at the target location; controls the OCT imaging system to acquire OCT data of a second portion of the retina which is stimulated by the applied optical stimulus during acquisition of the OCT data; and generates the ORG data based on the acquired OCT data.
