Abstract

We present a low-cost, high resolution, real-time Spectral Domain Optical Coherence Tomography (SDOCT) system optimized for rapid 3D imaging of the human retina in vivo. Using a source with an 841nm center wavelength and a FWHM bandwidth of 49nm, 6.67 second length bursts of 100 512 × 1000 pixel images were acquired with an integration time of 50 μs/line and a frame rate of 16 frames/sec. Three-dimensional data sets comprising up to 4.0mm × 1.2mm × 2.45mm retinal volumes were streamed to hard disk during this brief ocular fixation interval and post-processed to create 3D volumetric images of the optic nerve head and fovea.
