(a) Diagram of an optical diffractometer. D is the object (an electron micrograph), [M_{p}] is the diffraction plane and a mask that transmits only [\Phi_{hk}], [D_{p}] is the plane of the (filtered) image; (b) an electron micrograph of a crystalline layer of the protein phosphorylase b; (c) its optical diffraction pattern (the circles correspond to the windows in the mask that transmits only the [\Phi_{hk}] diffracted beams from the periodic component of the image); (d) the filtered image. Parts (b)–(d) are based on the article by Kiselev et al. (1971)[link].
