Fig. 3: OCT imaging of tape layers and a finger.
From: Shot-noise limited, supercontinuum-based optical coherence tomography
Single B-scans of tape layers (2 × 3 mm), obtained using the 80 MHz SuperK extreme (a), ANDi SC (b), and 320 MHz SuperK extreme (c) sources. Averaged A-scans within the 146 μm wide dotted box in (b) for the three sources offset by 5 dB (d). The average is taken over 49 A-scans equally spaced within the dotted box. Single B-scans of a finger where the nail begins (2 × 4.5 mm) [see photo (h)], obtained using the 80 MHz SuperK extreme (e), ANDi SC (f), and 320 MHz SuperK extreme (g) sources. Single B-scans of the rough skin on a hand palm (2 × 3 mm) [see photo (i)] obtained using the 80 MHz SuperK extreme (j), ANDi SC (k), and 320 MHz SuperK extreme (l) sources. Averaged A-scan (averaged over entire B-scan, corresponding to 1024 A-scans) of the rough palm skin for the three sources (m). Dashed ellipses mark the penetration depth
