Client

Figure 1.5: Client software part user interface.

Client software part is a program, with which user work. Because of this a special attention had been paid to developing this program and making it better.

This program can run under Windows 95, Windows NT and Window XP operating systems. TCP/IP protocol is used to connect to the server. This allow to connect to the server not only within local network, but also through Internet.

All scanning parameters, that were defined by user, are transferred to the server and then to a microscope and to other users, connected as clients. After the scanning process is started number of windows are open. In this windows different data are representing in real-time manner -- obtained images, their sizes, scanning mode, feedback parameters, current probe coordinates, scanning speed. At the same time user can process the data acquired using wide range of different functions, included in the program. Picture 1.5 representing client program main window during scanning process. Panels that shows current configuration and window with obtaining image can be seen.

Client-program has lots of different functions for SPM image processing and analysis. With this functions user can easly extract needed information from obtained data. These functions are listed in 1.1 table. If some sets of operations are used frequently it is possible to group these operations in single macro command, which can significantly decrease time loses.

Saving images to a clipboard
Saving images in BMP format
Exporting images to different formats


The program saves images in format compatible with Nanoscope-III file format, which is used on microscopes from Digital Instruments$^{TM}$. This allow to process obtained images with this rather wiedly spread SPM systems also. This concerned not only to surface images, but to one dimensional data ( $I_{tun}(Z), F(Z)$ and others) also.
