Editing Scanning electron microscope (section)

===Color built using multiple electron detectors===
In some configurations more information is gathered per pixel, often by the use of multiple detectors.<ref name="Antonovsky-1984">{{cite journal |last=Antonovsky |first=A. |year=1984 |title=The application of colour to SEM imaging for increased definition |journal=Micron and Microscopica Acta |volume=15 |issue=2 |pages=77–84 |doi=10.1016/0739-6260(84)90005-4}}</ref>

As a common example, secondary electron and backscattered electron detectors are superimposed and a color is assigned to each of the images captured by each detector,<ref name="Danilatos-1986a">{{cite journal |last=Danilatos |first=G.D. |year=1986 |title= Colour micrographs for backscattered electron signals in the SEM|journal=Scanning |volume=9 |issue= 3|pages=8–18|doi=10.1111/j.1365-2818.1986.tb04287.x|s2cid=96315383 }}</ref><ref name="Danilatos-1986b">{{cite journal |last=Danilatos |first=G.D. |year=1986 |title= Environmental scanning electron microscopy in colour|journal=Journal of Microscopy |volume=142 |pages=317–325|doi=10.1002/sca.4950080104|doi-access=free }}</ref> with a result of a combined color image where colors are related to the density of the components. This method is known as density-dependent color SEM (DDC-SEM). Micrographs produced by DDC-SEM retain topographical information, which is  better captured by the secondary electrons detector and combine it to the information about density, obtained by the backscattered electron detector.<ref name="Bertazzo-2013">{{Cite journal
