Abstract
An optical imaging device includes a plurality of imaging channels. Each imaging channel of the plurality of imaging channels may include a discrete optical imaging pathway, and the plurality of imaging channels may be disposed within a support structure. The plurality of imaging channels may be aimed at different angles relative to each other. The optical imaging device may also include a secondary fixation target within at least one imaging channel of the plurality of imaging channels such that at least one corresponding optical imaging pathway fits through a pupil diameter that is smaller than a minimum pupil diameter for multi-channel image acquisition with primary fixation.
