About: Ronchigram

An Entity of Type: Thing, from Named Graph: http://dbpedia.org, within Data Space: dbpedia.org

Ronchigram is the convergent beam diffraction pattern of a known object with features comparable to the diffracting wavelength. In the case of electron Ronchigrams amorphous materials are used. The structure of the Ronchigram encodes information about the aberration phase field across the objective aperture. As such, Ronchigrams have become increasingly important with the invention of aberration corrected scanning transmission electron microscopy.
