Abstract
High speed ophthalmic Optical Coherence Tomography systems are of interest because they allow rapid artifact free widefield retinal imaging. Space Division Multiplexing Optical Coherence Tomography is a high-speed imaging technology which takes advantage of the long coherence length of MEMs VCSEL sources to multiplex multiple images along a single imaging depth. We demonstrate widefield retinal OCT and OCT angiography imaging, acquired at effective Ascan rates of 800,000 Ascans/sec with imaging ranges of up to 11 x 7mm on the retina. A clinical study was conducted to compare ophthalmic SDM-OCT with commercial OCT and OCTa systems.
