摘要：

A simple method for converting an analog high-resolution electron energy loss (HREEL) spectrometer to a digital instrument is described in this paper. Methods of Fourier transform smoothing of the digital data are described and a comparision to RC-smoothed analog data is made using synthetic analog data. The advantages of digital data acquisition in HREELS compared to analog methods are presented. © 1990, American Vacuum Society. All rights reserved.
