sMoire for DigitalMicrograph

 

Higashimatsuyama, Saitama, Japan (April 28, 2016): HREM Research Inc. has announced that the STEM Moiré Analysis plug-in (sMoire) for DigitalMicrograph will be released on May 1, 2016.  The sMoire allows strain analysis to high accuracy from a single or a set of moiré images obtained by using STEM (Scanning Transmission Electron Microscope).

 

A Moiré pattern may be artificially generated in STEM by choosing the scan step (ds) close to the crystalline periodicity (d). The sMore measures fringe deformation from a single Moiré pattern using the technique developed for the GPA (Geometric Phase Analysis) for DigitalMicrograph. Furthermore, the sMore can calculate two dimensional strain maps using two geometric phases in a similar way to HoloDark (Dark-field Holography for strain) for DigitalMicrograph.

 

gWe have a series of strain measurement plug-ins for DigitalMicrograph (GPA, PPA and HoloDark),h says Dr. Kazuo Ishizuka, President of HREM Research Inc. gThe sMoire is the forth plug-in for strain measurement. Since atomic resolution STEM becomes increasingly popular these days because of ease of its operation, we believe the sMoire will become a major technique for strain measurement.h
