Figure 6

Measurement of 3D printed electrode sample using the low-cost LF-FD-OCT system. (a) Volume rendering image of the printed electrode sample. The three interfaces are corresponding to air/PDMS, PDMS/glass, and glass/air interfaces, and the PPY/PDMS structures are within the PDMS layer. (b) OCT B-scan image in the x–z plane extracted from the position indicated by the green line in (a). The area enclosed by the yellow line indicates a cross-sectional PPY/PDMS structure. (c) Height profile of isolated PPY structures. The color code displays the varying heights. (d) Left: OCT en face image in the x–y plane with the automatically marked PPY structures in red color; Right: Microscope image of the sample. The area enclosed by dotted lines in the OCT en face image represents the same area in the microscope image, which is 2.5 mm × 3 mm (x–y plane).
