Ultrahigh-resolution imaging of the human retina with scan modulation visible light optical coherence tomography (Conference Presentation)

We investigated clinical imaging of the human retina with visible-light optical coherence tomography (vis-OCT) with a 1 µm axial resolution. Imaging was performed with rectangular modulation of the scanning beam that reduced image speckle noise and preserved fine anatomical features. B-scans acquired with scan modulation revealed new anatomical features and demonstrated increased contrast to noise ratio (CNR) over regularly acquired B-scans.
