OCI BDL800IR User manual

Chapter 1 Introduction 3
Foreword
The LEED Software Data Acquisition and Analysis was developed for OCI Vacuum Micro-
engineering by Dr. Greg Hall.
The software acquires, saves, and analyzes LEED images. The images areMultLEED
stores as platform independent bitmaps (.bmp files), which can be viewed using other Win-
dows applications. Supported platforms are Windows XP and Windows 7.
MultLEED can perform analyses on LEED images such as adding and subtracting im-
ages, enhancing brightness and contrast, line scanning through the image, calculating lattice
distances, calculating IV curves and reliability factor calculations, and acquiring Intensity–
Time (IT) curves.
