High-speed polarization sensitive optical coherence tomography scan engine based on Fourier domain mode locked laser: erratum

Abstract

We recently reported on a new swept source polarization sensitive optical coherence tomography system and its application to skin imaging [Biomed. Opt. Express 3, 2987 (2012)]. In some of the tomographic images, two skin layers were labeled wrongly (interchanged). We present figures with corrected labeling.

We recently reported on a new swept source polarization sensitive optical coherence tomography system and its application to skin imaging [1]. In three of the tomographic images of that paper (Figs. 4, 5, and 6) two skin layers were wrongly labeled: epidermis (E) and dermis (D) were interchanged. We replace these figures by the correctly labeled figures, Fig. 1 , Fig. 2 , and Fig. 3 , respectively. The text sections of the paper are not affected by that error.

Fig. 1.

(Replacement for Fig. 4 in original manuscript [1]) PS-OCT images of human skin. Proximal interphalangeal joint of middle finger (PIP) region. (a)–(d) single frame images; (e)–(g) average of 15 frames. (a), (e) reflectivity (log scale); (b), (f) retardation (color scale: 0–90°); (c), (g) axis orientation (color scale: −90–+90°); (d) DOPU (color scale: 0–1), 2D DOPU window (12(x) x 6(z) pixels or 55 x 38 µm²); (h) photo of imaged area, line shows approximate B-scan position. Scale bar dimensions: 0.5 mm (x: geometrical distance; z: optical distance). SC, stratum corneum; ED, epidermis; D, dermis; CLS, “column” like structure.

(Replacement for Fig. 5 in original manuscript [1]) PS-OCT images of human skin. Nail fold region. (a) reflectivity (log scale); (b) retardation (color scale: 0–90°); (c) axis orientation (color scale: −90–+90°); (d)–(f) DOPU (color scale: 0–1). (d) 2D DOPU window (16(x) x 7(z) pixels or 96 x 44 µm²); (e) 3D DOPU window (8(x) x 4(y) x 3(z) pixels or 48 x 48 x 19 µm³); (f) 3D DOPU window (5(x) x 5(y) x 3(z) pixels or 30 x 60 x 19 µm³). Scale bar dimensions: 0.5 mm (x: geometrical distance; z: optical distance). SC, stratum corneum;, ED, epidermis; D, dermis.

(Replacement for Fig. 6 in original manuscript [1]) PS-OCT images of human skin. Fingertip region. (a) reflectivity (log scale); (b) retardation (color scale: 0–90°); (c) axis orientation (color scale: −90–+90°); (d)–(f) DOPU (color scale: 0–1). (d) 2D DOPU window (6(x) x 12(z) pixels or 48 x 75 µm²); (e) 3D DOPU window (4(x) x 4(y) x 6(z) pixels or 32 x 32 x 38 µm³); (f) 3D DOPU window (2(x) x 6(y) x 6(z) pixels or 16 x 48 x 38 µm³). Scale bar dimensions: 0.5 mm (x: geometrical distance; z: optical distance). SC, stratum corneum;, ED, epidermis; D, dermis; CLS, “column” like structure.
