surface topography measurement method whereby a conventional hologram resulting from the interference between a reference wave and an object wave reflected by a surface is recorded and processed digitally to reproduce the surface topography, pinnatopograafia mõõtemeetod, mille puhul standardne hologramm, mis tuleneb tugilaine ja pinnalt peegelduva objektlaine vahelisest interferentsist, salvestatakse ja töödeldakse digitaalselt, et reprodutseerida pinna topograafiat
