Claim:
1. A dual-modality imaging apparatus comprising: a reflectance confocal microscopy (RCM) imaging apparatus comprising a RCM source; an optical coherence tomography (OCT) imaging apparatus comprising an OCT source; a dichroic mirror configured to an imaging objective having a numerical aperture that is (a) underutilized in the OCT mode to permit imaging depths of greater than one millimeter, and (b) fully utilized in the RCM mode to permit high-resolution imaging, the dual-modality imaging apparatus thereby able to co-register the RCM and OCT images to permit simultaneous acquisition and display of RCM and OCT images, wherein underutilizing the numerical aperture in the OCT mode means utilizing between 6.7% and 10.7% of the numerical aperture in the OCT mode.
