Core Features of WSXM
Image Visualization and Processing
WSXM provides high-quality visualization options for microscopy data, allowing researchers to view images in 2D and 3D formats. It supports various color maps and scaling options to enhance the interpretability of surface features. The software includes tools for:
- Brightness and contrast adjustment
- Color mapping and shading
- Smoothing and filtering (e.g., Gaussian, median filters)
- Noise reduction techniques
These features enable users to enhance image quality and extract meaningful information from raw data.
Quantitative Surface Analysis
A significant aspect of WSXM is its ability to perform detailed surface analysis. Researchers can measure:
- Surface roughness parameters (e.g., Ra, Rq, Rz)
- Feature dimensions such as height, width, and area
- Step heights and terrace widths
- Curvature and slope analysis
These measurements are crucial in assessing material properties, surface modifications, and nano-structuring.
3D Surface Reconstruction
WSXM excels in generating three-dimensional visualizations from 2D data, providing a more intuitive understanding of surface morphology. Users can manipulate 3D models, rotate, zoom, and apply shading effects to reveal subtle surface features. This capability is essential for nanostructure characterization, quality control, and educational purposes.
Filtering and Noise Reduction
High-resolution microscopy images often contain noise that can obscure critical features. WSXM offers a suite of filtering tools to address this issue, including:
- Low-pass filters
- Median filters
- Fourier filtering
- Flattening and leveling routines
These tools help in obtaining cleaner images suitable for accurate analysis.
Automation and Customization
For repetitive tasks or complex data processing, WSXM supports scripting via macro languages. Users can automate workflows, perform batch processing, and customize analysis routines to suit specific research needs.
Supported Data Formats and Compatibility
WSXM is compatible with multiple data formats, including proprietary formats from various STM and AFM instruments. It also supports standard image formats such as TIFF, BMP, and PNG, enabling easy import and export of images. This flexibility ensures broad applicability across different microscopy setups.
Additionally, WSXM can integrate with other software tools for further analysis, such as MATLAB or ImageJ, through export functionalities.
