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 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
