Patent attributes
A retinal imaging system includes an eyepiece lens assembly, an image sensor, a dynamic fixation target viewable through the eyepiece lens assembly, and a controller coupled to the image sensor and the dynamic fixation target. The controller includes logic that causes the retinal imaging system to perform operations including: acquiring a first image of the eye, analyzing the first image to determine whether a misalignment between the eye and the eyepiece lens assembly is present; in response to determining the misalignment is present, adjusting a visual position of the dynamic fixation target to encourage the eye to rotate in a direction that compensates for the misalignment, and acquiring the retinal image of the eye after adjusting the visual position of the dynamic fixation target.
