Effective Wavelength Compensation: sensitivity vector directions are computed considering light bending and wavelength shortening due to refractive index transitions, but not accounting for the non-planar geometry of the specimen.
Bragg scatter results from radar returns from turbulent irregularities in the electron density with scales of half the projection of the radar wavelength onto the wave vector.
For the broadband light source considered, and using the relationship between spatial frequency, wave-vector, and wavelength explained in Section 2, the spatial-frequency bandwidth is 0.816 lp/ µm with the resulting coherence length being 1.225 µm.
where η0=y0/Vp, f dr m = − 2 ( V p − V a ) 2 / ( λ R 0 ), λ is the carrier wavelength, and ξm= r0y0VrVa) is a vector describing the parameters of the moving target.
Characteristics In order to illustrate single-scattering interference of relevance to the present study (Muinonen et al., 2007a; Tyynelä et al., 2007), we consider an electromagnetic plane wave (vector amplitude E0, wavelength λ, wave number k = 2π/λ, and wave vector k0) propagating along the z-axis and incident on a spherical scatterer located in the origin (Figs. 1 and 2).
The interferograms are then resampled from wavelength to a linear wavenumber vector (k = 2π/λ), and digitally corrected for chromatic dispersion [ 19].
Each EEM matrix has been concatenated into a single vector, by excitation wavelength, for all excitation-emission pairs – the resulting plotted line has 16 modes for the 16 excitation wavelengths.
where k is the scattering vector, λ is the wavelength of electron beam, Cs is the spherical aberration coefficient of a microscope, and ∆z is the defocus value.
In the momentum representation, which is preferred in quantum field theory, a photon is described by its wave vector, which determines its wavelength λ and its direction of propagation.
The precise condition is easiest to understand in terms of "wave vector," essentially one over the wavelength: The wave vector of the ripples must equal the difference in the wave vectors of the interfacial and surface waves.
