The flexible and modern open source scanning probe microscopy software package GXSM

GXSM is a full featured and modem scanning probe microscopy (SPM) software. It can be used both in stand alone mode for powerful image processing and analysis and connected to an instrument operating many different flavors of SPM, e.g., scanning tunneling microscopy and. atomic force microscopy or in general two-dimensional multichannel data acquisition instruments. The GXSM core can handle different data types, e.g., integer and floating point numbers. An easily extendable plug-in architecture provides many image analysis and manipulation functions. A digital signal processor subsystem runs the feedback loop, generates the scanning signals, and acquires the data during SPM measurements. In addition it performs sophisticated spectroscopy tasks such as scanning tunneling spectroscopy. The GXSM software is released under the GNU general public license and can be obtained via the Internet. (C) 2003 American Institute of Physics.
