(A) Native path length multiplexed SAR-OCT image contains three sub-images, each with a different path length (L, H2, and H3). (B) Eight repeating B-scans collected for angiography are averaged and displayed as a single OCT retinal image in logarithmic scale. (C) The averaged retinal image is segmented using a custom semiautomatic algorithm. The axial scale bar is 300 µm; the lateral field of view is 1.3 mm (37°). Signal amplitude in pathlengths 1 and 2 are maximized and balanced to encode more discernable scattering information. ILM, internal limiting membrane; INL, inner nuclear layer; OPL, outer plexiform layer; RPE, retinal pigment epithelium. Reproduced with permission from Gardner et al.⁴⁶
