What is Mosaic Field of View SEM Imaging?
Mosaic Field of View SEM imaging is a powerful technique bridging XRM and FIB-SEM to ensure sample representativeness at the right resolution.
In the video above, we show a MFV-SEM image collected on a sandstone sample after argon mill polishing. A total of 35,000 by 27,000 pixels was stitched from a few hundred SEM tiles at a 100 nm resolution. Within DigiM I2S software, the supervised machine learning module segmented the large image into different phases to quantify porosity and mineral grains.
Benefits and Challenges
- Large field of view of millimeter to centimeter and nanometer in resolution
- Argon mill to prepare an artifact-free surface
- EDS chemical characterization can be used in conjunction
- Bridging technology between XRM and FIB-SEM
- Full support of online visualization, AI segmentation, quantification, sharing, and storage through I2S software
- 2D technique
- Large dataset (for example: 25,000 x 25,000 pixels) that cannot be easily viewed without cloud computing
- Destructive technique that requires vacuum during imaging; thus, limiting samples to solids
