Diagram of a Prototype Space-Division Multiplexing Optical Coherence Tomography (SDM-OCT) System

Caption

(a) Diagram of a prototype space-division multiplexing optical coherence tomography (SDM-OCT) system, an ultra-high speed biomedical imaging technology that can achieve >10x speed improvement using parallel imaging while preserving resolution and sensitivity. (b) A 1x8 fiber array was used to achieve 8x speed improvement. (c) Each beam was optically delayed. Signals from different beams, corresponding to different sample locations, were presented at different frequency range (i.e. imaging depth). High speed was achieved with parallel imaging beams. For simplicity, only 4 beams are shown in the figure.
