The 'speckleometer': a compact, portable surface roughness measurement unit based on angular speckle correlation
A compact, portable surface roughness device has been designed and constructed, which uses an angular speckle correlation method to measure the RMS surface roughness of grit-blasted steel surfaces. The unit uses an innovative wedge design to generate an angular difference in illumination of the surface. It was demonstrated that the unit could measure surface roughness to within ∼2 μm of reference RMS roughness measurements made using a surface profileometer.
