Domain metrologymeasuring instruments
  • kõver, mis kirjeldab mõõtevahendi kõrgustundlikkust pinnatopograafia ruumsagedusfunktsioonina
  • curve describing an instrument's height response as a function of the spatial frequency of the surface topography
  • function of spatial frequency describing how a surface topography measuring instrument responds to an object surface topography having a specific spatial frequency
mõõtevahendi ülekandeseos preferred
Usage examples
  • Ideaalis iseloomustab mõõtevahendi ülekandeseos seda, milline oleks määratud ruumilise sagedusega ν sinusoidse difraktsioonvõre mõõtmisel saadud kõrgus tegeliku kõrguse suhtes.
