Abstract

A high-speed (47,000A- scanss), ultrahigh axial resolution Fourier domain optical coherence tomography (OCT) system for retinal imaging at 1060nm, based on a 1024  pixel linear array, 47kHz readout rate InGaAs camera is presented. When interfaced with a custom superluminescent diode (λc=1020nm, Δλ=108nm, Pout=9mW), the system provides 3.3μm axial OCT resolution at the surface of biological tissue, 4.5μm in vivo in rat retina, 5.7μm in vivo in human retina, and 110dB sensitivity for 870μW incident power and 21μs integration time. Retinal tomograms acquired in vivo from a human volunteer and a rat animal model show clear visualization of all intraretinal layer and increased penetration into the choroid.
