Introduction A partially coherent source whose degree of coherence between two points is shift-invariant (i.e., depends only on the difference between the position vectors of the two points) is said to be of the Schell-model type [ 1 ]. WebAbstract. A flexible pseudo-mode sampling superposition method for synthesizing partially coherent sources has been introduced that can be thought of as an approximate …
WebThis work introduces a new class of partially coherent beams whose spectral density and degree of coherence tend to rotate during propagation, and it is shown that such beams can undergo a twist of more than 90 deg, providing larger degrees of freedom for flexibly tailoring the beam twist. 37 WebThe propagation problem of a partially coherent field can be solved with the help of the Green’s function formulation [ 141 ], i.e. W ( r 1, r 2, ω) = ∫ ∫ G ∗ ( r 1, r 1 ′, ω) ⋅ W ( 0) ( r 1 ′, r 2 ′, ω) ⋅ G T ( r 2, r 2 ′, ω) d 2 r 1 ′ d 2 r 2 ′, where the Green tensor G ( r, r ′, ω) is a spatial transfer function between the coherence matrix W …
WebPartially coherent sources with radial coherence are proposed. They present a circularly symmetric intensity profile and a degree of coherence whose absolute value only depends on the angular difference between the two considered points. In particular, the source is completely coherent at pairs of points belonging to the same radius. The modal …
