  The surface roughness is an important parameter for examining the quality of material surfaces.Though the surface roughness is generally measured by a stylus profiling technique,optical technique,or laser microscopy technique,these methods are only applicable to the accessible surface.On the other hand,the back surface roughness is also important for evaluation of the quality of products,condition of corrosion or degradation.
