Bio‐Inspired Magnetically Tunable Structural Colors from Elliptical Self‐Assembled Block Copolymer Microparticles

open access: yesAdvanced Functional Materials, EarlyView.
Cephalopod‐inspired photonic microparticles with dynamic structural coloration are fabricated via confined self‐assembly of linear block copolymers into ellipsoids containing stacked lamellae. Embedded superparamagnetic nanoparticles enable rapid magnetic alignment, restoring vivid, angle‐dependent color.

Reconstruction in diffraction imaging

IEEE Transactions on Ultrasonics, Ferroelectrics and Frequency Control, 1989
The problem of reconstruction in imaging systems that are modeled using the Helmholtz wave equation (diffraction imaging) is addressed. A spectral analysis of the available diffraction data is presented to help develop algorithms and constraints on a diffraction imaging system's parameters for accurate reconstruction of the desired image.

Diffraction Imaging in Depth

69th EAGE Conference and Exhibition incorporating SPE EUROPEC 2007, 2007
ABSTRACTHigh resolution imaging is of great value to an interpreter, for instance to enable identification of small scale faults, and to locate formation pinch‐out positions. Standard approaches to obtain high‐resolution information, such as coherency analysis and structure‐oriented filters, derive attributes from stacked, migrated images.
