Unwrapped OPD maps of an air-filled PDMS microfluidic channel. (a) 6207 nm synthetic-wavelength OPD map, unwrapped by a standard unwrapper38. (b) Hierarchically-unwrapped OPD map. Scale and color bars apply to both OPD maps. Red rectangles indicate region of overlap between FOVs. (c) OPD value profile curves along dashed horizontal green lines in (a) and (b). (d) OPD value profile curves along dashed vertical cyan lines in (a) and (b).
