Using a radial array of electron detectors, we can deconstruct and spatially resolve the entire electron scatter field emitted from the surface of a sample.  After color-coding the electron detection profiles from multiple angles, we can subsequently  recombine these signals for the generation of a polychromatic electron micrograph where variability in surface topography is revealed in a dazzling array of hues.  The high angular sensitivity of this technique permits the effective illustration of subtle differences in surface profile in structurally heterogenous materials.  PCSEM.html
