More powerful data analysis is carried out in lifeAnalysis, an interface program developed for the Interactive Display Language (IDL) system. |
When a scan is completed, the data can be transmitted directly to the lifeAnalysis program and results obtained in time to influence parameters for the next scan.
- Quantitative color coding of any of the mapped variables
The table of heights at which colors change are selectable from an array of sets. Transitions can be gradual for fine detail or discontinuous for contouring. When resolution has been achieved, quantitative spectrum height representation is a valuable tool.
- Local Gaussian averaging
If desired, the value at each pixel can be replaced by a local average, suppressing noise as a tradeoff against lateral resolution. Local averaging extending only as far as neighboring pixels, and leading to noise reduction of a factor of 2 or less, are most useful.
- Three-dimensional color-contoured images
3D available at an arbitrary view angle and z-scale
- Distance and height measurements in pixels and nm
- "Sections" plots of height vs. position for an arbitrary path
This is the most reliable method for height measurement of a feature. Sections can be created for arbitrary lines chosen by the operator. Both plot and a table of height values each nm are provided.
- Molecule projected areas and volume
They require careful correction for tip width.
- True plane-fits made to the substrate
- Comprehensive statistical analysis and a wide range of mathematical operations
IDL is a simple, powerful and easily learned programming language. If an experiment requires a new derived quantity or distribution or display, it can be provided, usually with a few new statements.
