Abstract
An optical imaging device includes a support structure and imaging channels, where each imaging channel includes a discrete optical imaging pathway. The imaging channels may be disposed within the support structure, and the imaging channels may be aimed at different angles relative to each other such that each optical imaging pathway is directed towards a pupil of the eye. Additionally, the optical imaging device may include a primary fixation target configured to emit optical signals along a primary fixation target projection path towards the pupil of the eye. Further, an artifact of the primary fixation target may be generated onto a portion of the eye to be imaged.
