Paper Abstract
Optical digital-imaging techniques offer a fast, high-resolution, and wide-range metrology capability for measuring
semi-transparent and transparent polymer-based devices during manufacture. This work presents novel instrumentation
for in-process statistical control and metrology capable of measuring a complete macroscale part (~25 mm) down to its
microscale features (~50 μm). The high speed 2.5D profilometer has generated contour plots with 0.4 μm lateral and 1
μm vertical resolution. The instrument has an estimated data rate of 8 million 3D data points per second, approximately
270 times faster than conventional white light interferometry.
