Query: RTSPM: Real-time Linux control software for scanning probe microscopy   Real time computer control is an essential feature of scanning probe
microscopes, which have become essential tools for the characterization and
investigation of nanometer scale samples. Most commercial (and some
open-source) scanning probe data acquisition software uses digital signal
processors (DSPs) to handle the real time data processing and control, which
adds to the expense and complexity of the control software. We describe here
scan control software that uses a single computer and a data acquisition card
to acquire scan data. The computer runs an open-source real time Linux kernel,
which permits fast acquisition and control while maintaining a responsive
graphical user interface. Images from a simulated tuning-fork based microscope
as well as a standard topographical sample are also presented, showing some of
the capabilities of the software.
