Normalized reflectance images at (a) $\lambda =650\mathrm{nm}$ and (b) $\lambda =1000\mathrm{nm}$ (Video 3, AVI, 1.3 MB) [URL: http://dx.doi.org/10.1117/1.JBO.20.12.121312.3] and (c) ${\mathrm{SO}}_2$ map at 8 h after adding yeast to the ${\mathrm{HbO}}_2$ solution (experimental configuration 2). Arrows indicate the effect of deep channel on both reflectance image and saturation map.
