Fig. 5
(a) Side-view picture of the device during the assembling procedure. The fluorescence profile of the light-sheet generated by the rhodamine dye is visible in the channel. In the inset is reported the bottom view of the light-sheet during the assembling procedure. This view shows a non perfectly uniform illumination. (b) Schematic of the setup used for the pattern visualization inside the microfluidic channel. (c) ROI of the cross section (bottom view of the light sheet in the channel) picture acquired with a high NA objective. Even if the illumination is not uniform, the modulation given by the interference is clearly visible. The scalebar is 10 \(\upmu {\rm m}\). (d) The graph reports the intensity (in gray levels of the camera) along the red line indicated in panel (c)..
