Abstract:
1. An optical coherence tomography (OCT) imaging system for imaging an eye, the system comprising: a source having an associated source arm path; a reference arm having an associated reference arm path coupled to the source path, the reference arm path having an associated reference arm path length; a sample arm having an associated sample arm path coupled to the source arm, the sample arm comprising at least one lens, wherein the at least one lens has an associated focus adjustment configured to enable imaging a retina in one focal setting and to enable imaging a structure anterior to the retina within the posterior chamber in a second focal setting; and a reference arm path length adjustment module coupled to the reference arm, wherein a range of the reference arm adjustment is at least 15 mm; wherein 15 mm defines a optical path length difference between and eye length of a premature infant eye and an eye length of an adult eye; and wherein the reference arm path length is adjusted coarsely to accommodate an eye length and finely to adjust to a prescribed offset between a reference position and a focal plane within the sample of the at least one lens.
