J. Hesse et al., Evaluation of scanners and CCD cameras for high-resolution TEM of protein crystals and single particles, MICROSC RES, 49(3), 2000, pp. 292-300
The modulation transfer function (MTF) and the geometric errors of two flat
bed scanners, a slow-scan CCD (SSC) camera and film, have been measured and
compared. The geometric errors of the SSC camera and film have been measur
ed using diffraction spots from a lipid crystal. The SSC camera was shown t
o have the smallest geometric errors while film had the best MTF. Even thou
gh film had the best MTF, this is significantly reduced when scanning the f
ilm, so that the MTF of the film and scanner combined are comparable to the
MTF of the SSC camera. Microsc. Res. Tech. 49:292-300, 2000. (C) 2000 Wile
