Furthermore, imaging sequences and montage generation, etc., may be compromised by eye motion relative to small fields, which may not be fully addressable in post-processing due to poor overlap, especially with noisy or low-contrast images or slower scanning modalities (e.g., AO-OCT). To cover wider angular ranges, the eye itself must move (rotate) guided by a fixation target at some retinal conjugate in the optical system.

modest field of regard-that is, the angular range of ac- cess to the retina is restricted by angle-limiting mirror diameters, and as a consequence, fields of regard are not much larger than image fields of view.
