In particular, for a Gaussian beam the phase shift deviates from that of a plane wave by the so-called Gouy phase shift [1]:φG(z)=−arctanzzR where zR is the Rayleigh length and z = 0 corresponds to the position of the beam waist. As can be seen in Figure 1, that term...
We have investigated the effect of phase shift selection and phase shift errors on wave-front reconstruction errors in three-step generalized phase-shifting interferometry (GPSI) systematically. A general formula of the mean square wave reconstruction error for different phase shift selection and ...
Second, the interface area formula can be expressed, as discussed before by the Cahn–Hilliard energy functional given in (10). Other frequently used geometric quantities include the interface normal, expressed by ∇uɛ/|∇uɛ|, and as already mentioned above, the formula for the mean ...
In this subsection, we explore the application of GTIE for phase retrieval under partially coherent illuminations. It should be emphasized that the major concern in such scenario is the well-defined phase shift introduced by the specimen, rather than the generalized phase of the partially coherent ...
phase shift in neural output. Evidence towards this notion would advance our understanding of phase precession in humans and how it relates to functional processes. For this, three key questions must be addressed: First, are phase preferences of neural firing shifted during application of external ...
The red phase trace at the cut-off frequency is defined as the frequency point where the capacitive reactance and resistance are equal R = XC, the phase shift is 90° following the formula:ϕ2=tan−1(2πfRC)ϕ2=tan−1(2πfRC)...
the channelhas a sufficiently strong attractive interaction and can lead to a quasi-bound state with the iterated methods, as shown in Refs. [65,73,74,75,76,77,78,79]. Note that a repulsive interaction has a negative scattering length or phase shift in our convention. The scattering length...
