'''Realspace''' or '''direct-space''' is simply the regular 3D space that we inhabit. In scattering, it is introduced as a term to differentiate from [[reciprocal-space]] (a.k.a. inverse-space). Whereas reciprocal-space refers to the [[Fourier transform]] of the sample's structure, realspace refers to the actual structure: the electron-density spatial distribution (as imaged in SEM, TEM, AFM, STM, etc.).

Example realspace image (SEM) of a block-copolymer pattern etched into silicon.

Realspace or direct-space is simply the regular 3D space that we inhabit. In scattering, it is introduced as a term to differentiate from reciprocal-space (a.k.a. inverse-space). Whereas reciprocal-space refers to the Fourier transform of the sample's structure, realspace refers to the actual structure: the electron-density spatial distribution (as imaged in SEM, TEM, AFM, STM, etc.).
