Abstract
Systems for imaging a sample are provided. The system includes an optical coherence tomography (OCT) imaging portion having an associated OCT path defined by one set of optical elements between an OCT signal delivery optical fiber and the sample; an image capture portion having an associated image capture path defined by a second set of optical elements between an image capture device and the sample, different from the OCT path; and an illuminator portion having an associated illumination path defined by a third set of optical elements between an illumination source and the sample. The OCT path, the image capture path, and the illuminator path have at least one optical element in common, and the respective paths differ from each other by at least one optical element. The OCT path and the image capture path share a common intermediate conjugate image plane. Focal control is achieved for the OCT path and the image capture path concurrently through adjustment of one or more common optical elements distal to the common intermediate conjugate plane, such that focal control requires no differential adjustment between optical elements not in common to both paths.
