The phase and amplitude (Ph–A) of a wave function vary slowly with distance, in contrast to the wave function that can be highly oscillatory. Hence the Ph–A representation of a wave function requires far fewer computational mesh points than the wave function itself. In 1930 Milne presented...

Unlike DHM, ptychography reconstructs the phase and amplitude of a scattered wavefield without the need of a reference wave and is therefore inherently more stable, less prone to artefacts and optically less complex thus enabling easy modification of standard microscopes and can be used in conjunction...
Measuring amplitude and phase of continuous ultrasonic waves with a lock-in amplifier is shown to give similarly sensitive indicators of concrete damage as pulsed coda wave analysis, but maintains its sensitivity at considerably much lower signal levels. Continuous and pulsed measurements were performed ...
When a material object is placed in the path of an electromagnetic wave, the latter undergoes a change in both its amplitude and its phase. In particular, calculations have been performed previously for two extremes (1) to obtain the contrast caused purely by the change in amplitude produced ...
Scanning tunneling microscopy—freeze-fracture replication has provided a quantitative, high resolution description of the wave form and amplitude of rippled bilayers in the Pβ′ phase of dimyristoylphosphatidylcholine. The ripples are uniaxial and asymmetric, with a temperature dependent amplitude of 2.4...
s experiment provides practical experience with the meaning of magnitude and phase in a linear circuits and the use of phasor algebra to predict the response of a linear system to a sinusoidal input. Using the digital oscilloscopes, we can better understand the true implications of amplitude and...
Wide-angle elastic wave one-way propagation in heterogeneous media and an elastic wave complex-screen method (2) For P-S and S-P conversions, the screen is no longer a pure phase-screen and becomes complex (with both phase and amplitude terms); both ... RS Wu - 《Journal of Geophysical...

In this work, we propose a novel quantum-correlation enabled Fourier Ptychography technique, to capture high-resolution amplitude and phase images with a few photons. This is enabled by the heralding of single photons combined with Fourier ptychographic reconstruction. We provide experimental ...
