Figure 1 (A) Photograph of an ocular coherence tomography (OCT) device. This is a photograph of the Lightlab (Westford, Massachusetts) imaging engine. (B) Photograph of an OCT catheter. This figure is a photograph of a 0.017-inch OCT imaging catheter/guidewire consisting of relatively simple fiber optics. This includes a gradient index (GRIN) lens, single mode optical fiber, prism, and speedometer cable. (C) Schematic of a traditional OCT system. Ocular coherence tomography works via the technique of low coherence interferometry as described in the text.
