Since the seminal work of John Nye and Michael Berry in 19741, it was realised that such topological defects could emerge in any wavefield irrespectively of its physical nature or its dispersion relation. Wavefront dislocations have been observed from the physics of fluids, sound, electromagnetism ...
Adaptive optics (AO) is critical in astronomy, optical communications and remote sensing to deal with the rapid blurring caused by the Earth’s turbulent atmosphere. But current AO systems are limited by their wavefront sensors, which need to be in an optical plane non-common to the science i...
Fig. 13.13 shows significant wave variation cross-front with a maximum significant wave height of 1.2 m and a gradient current of 0.9 m s− 1. March represents the northeast monsoon period as coastal water currents in the South China Sea tend to move from the north [5]. Fig. 13.13 ...
The output for the previous execution looks like the wavefield shown in the following figure. It shows a circular wavefront propagating from a source in the middle of the square grid. It was plotted using the output ofiso2dfdusing the SU Seismic processin...
Although holography allows 3D wavefront modulation in the form of a reconstructed 3D object distribution, it does not provide a straightforward approach for creating arbitrary 3D intensity beams, and it is not employed to create such intensity modulations. Only the limited class of 3D curves that ...
The intrinsic contradiction between small objective distance and limited DOF is able to be avoided in wave-front coding approach, which establishes on the manipulation of point spread function (PSF) engineering in combination with post-digital processing procedure [11,12]. This proposal employs a ...
He’s one of Dick’s “minor men,” unable to manage his own life; in fact, he owes money to his own front door! Joe has a thing for his new colleague, Pat, who can change the past in such a way that people don’t realize it. Sent to Luna in search of criminal telepaths, ...
The statistics of the offshore wave climate is very essential information outside the harbour for all water front planning. It can only be obtained either by instrumental wave measurement or by wave hindcasting. In Indian context, for a long time, synoptic coverage of wind data over an area ...
A wavefront is the set of all locations in a medium where the wave is at the same phase. This could be where all the crests are, where all the troughs are, or any phase in between.
Add in Kaoss Physics and the Pitch Bend and Modulation Wheels, and you’ll always have multiple dimensions of realtime expression. Want to dig deeper? Almost all front-panel knobs, and most on-screen parameters, can be modulated. You can even modulate settings for individual Motion Sequence St...
