Comparison of HiScan & ZI scanners

The same micrograph was scanned in both the HiScan and ZI scanners.
Overview #2 was extracted from the ZI scan for comparison.

HiScan file ZI file, overview #2

size (pixels) 5336 x 6836 5546 x 7145

pixel size (A) 2.93 2.82

	HiScan file	ZI file, overview #2

Comparison of rotationally averaged power spectra:

Note that the zeroes (minima) in the ZI scan are better defined and are discernible at higher resolution. (Scales are slightly different due to the different pixel sizes.)
