Wide-field ophthalmic space-division multiplexing optical coherence tomography
Fig. 1. (a) Schematic for the ophthalmic SDM-OCT system. BOA, booster optical amplifier; FBG, fiber Bragg grating; MZI, Mach–Zehnder interferometer; PD, balanced photodetector. (b) Picture of the ophthalmic SDM-OCT prototype in the clinic.
Fig. 2. Geometric considerations for ophthalmic SDM-OCT design. (a) Projection of the curvature of the eye onto the imaging space. (b) Image space separated into four imaging beams with 3 mm optical delay. All four beams fit in the 12 mm image depth. (c) Distance between adjacent beams shows there is no overlapping between adjacent images. (d) Sensitivity roll-off measured over the entire imaging depth range.
