Optical Tomography of Photon-Added Coherent States, Even/Odd Coherent States and Thermal States [PDF]

open access: yes, 2011
Explicit expressions for optical tomograms of the photon-added coherent states, even/odd photon-added coherent states and photon-added thermal states are given in terms of Hermite polynomials. Suggestions for experimental homodyne detection of the considered photon states are presented.

Non‐Destructive and Mechanical Characterization of the Bond Quality of Co‐Extruded Titanium‐Aluminum Profiles

open access: yesAdvanced Engineering Materials, EarlyView.
This study investigates the bond quality of co‐extruded aluminum–titanium hybrid profiles, focusing on the lateral angular co‐extrusion (LACE) process. It examines how heat treatments (HT) affect intermetallic phase formation, bond strength, and material properties.

Mathematical Modelling of Optical Coherence Tomography

open access: yes, 2014
In this chapter a general mathematical model of Optical Coherence Tomography (OCT) is presented on the basis of the electromagnetic theory. OCT produces high resolution images of the inner structure of biological tissues. Images are obtained by measuring

Partitioning and Coarsening Dynamics of Precipitate‐Strengthened Cr‐Si Alloys: The Role of Ge, Pt, and Mo

open access: yesAdvanced Engineering Materials, Volume 27, Issue 9, May 2025.
The microstructure of Cr‐rich Cr‐Si‐alloys is maintained by alloying with Ge, Pt, and Mo. The effects of these elements on A15‐phase fraction, partitioning, microstructural stability, grain size, and hardness are combinable. Molybdenum is found to be the most promising alloying element for microstructural stability during high‐temperature exposure.

Analysis of Temperature and Stress Distribution on the Bond Properties of Hybrid Tailored Formed Components

open access: yesAdvanced Engineering Materials, EarlyView.
Hybrid materials enable high‐performance components but are challenging to process. This study explores an inductive heating concept with spray cooling for steel–aluminum specimens in a two‐step process including friction welding and cup backward extrusion.
