The high-spatial--fregiency behavior of rrethanical-profiling instrunents is determin principal ly by the non-linear geaitrica1 interaction beten the styl us tip and the surface irreularities. 'there is cons iderable interest in the nature of this interaction and its effects in practical applications. This paper explores the these issues analytically and pesents a riety of results with enphasis on the freuency-danain description. Smooth surfaces are treat1 by perturbation theory and are found to be rot4iened by tip-s ize effects , tiile rough surfaces are snoothed. In lieu of closel fotm results for rot4i surfaces, offer a simple conjecture rerding the nature of tip-s ize distortions and the rnaxinurn useable spatial freuenoj.
