Combined confocal/en face T-scan-based ultrahigh-resolution optical coherence tomography in vivo retinal imaging

Opt Lett. 2006 Jun 1;31(11):1684-6. doi: 10.1364/ol.31.001684.

Abstract

Combined confocal scanning ophthalmoscopy/en face T-scan-based ultrahigh-resolution optical coherence tomography (OCT) of the human retina in vivo is reported for the first time to our knowledge. The system uses a superluminescent diode-based broadband source, which gives an axial resolution of 3.2 microm in the retina. We demonstrate acquisition of T-scan-based OCT B-scan and simultaneous confocal/C-scan images of the human retina of large lateral size (covering a field of up to 20 degrees ) at a frame rate of 2Hz.
