We demonstrate analytically and numerically that the transverse spatial coherence (the spectral degree of coherence) of the field radiated by two partially correlated electromagnetic sources oscillates as a function of propagation distance in free sp

We demonstrate that two strongly correlated sources may generate a field with practically zero correlation between certain pairs of points. We argue that this is a general phenomenon in radiation and scattering.

When light that is spatially partially coherent, such as sunlight, is incident on a sphere, the scattered field exhibits surprising coherence properties. The observed oscillatory behavior with deep minima means that the field in certain pairs of dire

Code-Validation Scalar Measurements in High-Pressure Hydrogen-Added Methane Combustion
Autor: J.-Y. Chen, Jun J. Kojima, David G. Fischer
Publikováno v: Journal of Propulsion and Power. 33:285-304
The latest combustion model-validation experiments are presented using a time-, space-, and polarization-resolved subframe-burst gating Raman spectroscopy system. A modification to the original subframe-burst gating diagnostics system enables paralle

Detection of spacecraft fire signatures and post-fire aerosols—Part I: Ground-based results
Autor: David G. Fischer, Paul S. Greenberg
Publikováno v: Fire Safety Journal. 75:36-44
Preventing fires in spacecraft and other remote platforms is an important facet of avoiding fires that potentially compromise missions, hardware, and crew. If a fire occurs, the objective is to detect the associated fire signatures at the earliest po

We study the Gouy phase of a scalar wavefield that is focused by a lens suffering from primary spherical aberration. It is found that the Gouy phase has different behaviors at the two sides of the intensity maximum. This results in a systematic incre
