Fig. 3.
Zebrafish imaging results. (a)-(c) are the intensity, birefringence, and DOPU images without refocusing, respectively. (d)-(f) are the corresponding images with computational refocusing. Orange arrowheads indicate particles with strong reflection. Red arrows indicate the gill filament and yellow arrows the operculum. Black arrows indicate projection artifacts of birefringence and DOPU caused by structure superior to the imaged slice. White arrows indicate areas adjacent to the operculum, which might be operculum musculature or adductor mandibulae. Abbreviations: O, operculum; S, skin; GF, gill filament; PM, pectoral fin muscle. Scale bar denotes 500
