Due to the bandwidth of our connection

QUBE looks considerably less fluid as it is in reality

ESPRIT QUBEPlease note

What is QUBE ?

• For post processing of data sets acquired by analytical scanningelectron microscopy

• For 3D reconstruction of tomographic dataacquired by surface techniques such as EBSD and EDS

• Integrative analysis of 3D data sets

• Interactive processing pipeline

• Simultaneous operation on multiple data set types

ESPRIT QUBEData files

7

Import 2D data sets:

• EBSD: Bruker format (.bcf) and other common formats (e.g .ctf)

• EDS: Bruker (.bcf)

• SEM Images: common bitmap formats (.bmp, .gif, .png, .jpg etc.)

3D project:

• All 3 data types are saved into a single 3D project (.qml)

• .vti export, (.hdf5 planned)

• Export of images, lists and intermediate results

ESPRIT QUBEViewing & navigation

8

Viewing:

• “Real time” voxel rendering (wysiwyg)

• Extensive color codes for EBSD, EDS and SEM images

• Semi transparency for scalar data fields(e.g. see only areas of high GND density)

Navigation by:

• Tomography (slicing, cut outs etc.)

• Voxel-wise: 3D cursor

• Grain-wise: “grain neighborhood”

ESPRIT QUBEFilters and geometry

9

Geometry editing:

• Affects EBSD, EDS and SEM data sets

• Cropping and slice deletion

• Slice re-alignment (based on EBSD data)

Data filtering:

• Currently for EBSD data only

• Linear filters (Gaussian, box)

• Non linear filters (Kuwahara, median)

• Despeckling (outliers)

ESPRIT QUBEAnalytical tools

10

Analysis of EBSD data:

• Grain segmentation (extensive grain list)

• Local average disorientation (LAD)

• Approximated GND density (based on LAD)

• Schmid factor

• Subsets

Voxel subset options:

• Predefined subsets: textures, LAD, grain metrics, grain texture, grain neighborhood

• Save and copy customized subsets within project

• Export/import subsets

• Apply subsets across data sets

(e.g. EBSD grain subset in EDS data set)

ESPRIT QUBESubsets

11

Data compatibility:

• Signals whether derived child data is still in sync with parent data.

History:

• Data operations are logged sequentially in project file.

Reversibility:

• Data changing operations can be undone.

ESPRIT QUBEData monitoring

12

Multiple data sets:

• Multiple: EBSD and/or EDS and/or SEM images

• Operate on multiple data sets simultaneously(currently limited to the data editing operations)

• Apply subsets across data sets (e.g. apply EBSD subset on EDS data set)

• Viewing 2 data sets simultaneously by color blending(e.g. blend EBSD with SE data set)

Summary

• Tool for post-acquisition analysis of tomographic data sets

• Multiple data sets: EBSD, EDS, SEM images

• Wysiwyg

• Extensive subset possibilities

• Data monitoring

• Ever growing functionality
