Weighted ellipse fitting routine for spotty or incomplete Debye-Scherrer rings on a 2D detector
Phani S. Karamched, Yi Xiong, Chi-Toan Nguyen +3
We introduce a weighted ellipse fitting routine to measure Debye Scherrer rings acquired on 2D area detectors and demonstrate its use in strain determination. The method is relativ…

Non-contact, non-destructive mapping of thermal diffusivity and surface acoustic wave speed using transient grating spectroscopy
Abdallah Reza, Cody A. Dennett, Michael P. Short +5
We present new developments of the laser-induced transient grating spectroscopy (TGS) technique that enable the measurement of large area 2D maps of thermal diffusivity and surface…
