Fig. 1. Schematic diagram of the SLO guided Vis-OCT system^[54]

Fig. 2. Schematic of the VN-OCT system^[56]

Fig. 3. Overview of dual-channel Vis-OCT^[64]. (a) Schematic of the system configuration. Three key enabling designs for full-range and wide-field imaging are: ① linear-in-K Vis-OCT spectrometer; ② per-A-line noise cancelation by a second spectrometer; ③ reference pathlength modulation. Summary of the imaging performance by three optical designs: (b) achieving 7.2 dB signal-to-noise ratio roll-off over the entire imaging range; (c) short-noise limited performance; (d) doubling the imaging depth range
