Fig. 3 — Phantom experiments to compare the results obtained from two different laser sources: a small laser diode (L785P25) placed on the phantom surface versus a long-coherence DCS laser (DL785-100) coupled with an optical fiber. (a) Experimental setup (right) and configuration (left) of contact DSCF and DCS probes. Bland–Altman plots for the comparisons between relative flow changes measured by the (b) L785P25/DSCF and DL785-100/DSCF, (c) L785P25/DCS and DL785-100/DCS, and (d) L785P25/DSCF and DL785-100/DCS.
