Utilizing a commercial optical CCD camera with the smallest pixel size
presently available (6.8 x 6.8 mu m(2)) we have measured impact accur
acies of 0.9 mu m (rms) for 15 keV synchrotron radiation in direct pho
ton counting mode. Of crucial importance was diffusion spreading of th
e deposited charge such that by centroid reconstruction interpolation
between discrete pixel coordinates was possible.
