A non-destructive method used to estimate internal surface roughness of a small hole (0.2 mm in diameter and 0.7 mm in depth) is described. The first step of this method is to reconstruct a shadow pattern image of the internal surface from a series of optically sectioned images of the surface. The surface roughness parameters are then calculated from this shadow pattern image. The method is verified by measuring a known flat surface and comparing the results with stylus measurements.
