Abstract:
1. A system for imaging a subject, the system comprising: two imaging paths, a scanning beam optical coherence tomography (OCT) imaging path and a video imaging path, wherein the scanning beam OCT imaging path comprises: wherein the video imaging path comprises: a dichroic beamsplitter configured to couple the scanning beam OCT imaging path and the video imaging path, wherein the scanning beam OCT imaging path and the video imaging path share a common objective lens; wherein the scanning beam OCT imaging path and the video imaging path share a common intermediate conjugate image plane between the dichroic beamsplitter and the subject; wherein focal control is achieved for the scanning beam OCT imaging path and the video imaging path concurrently through adjustment of one or more common optical elements distal to the common intermediate conjugate plane; wherein the illuminator is a fiber ring illuminator; wherein a ring of illumination for the fiber ring illuminator is coaxial with the scanning beam OCT imaging path over a region where the scanning beam OCT imaging path and the video imaging path are in common; and wherein the fiber ring illuminator comprises a ring of optical fibers that defines an annulus.
