WebCausality and the Kramers-Kronig relations. Causality describes the temporal relationship between cause and effect. A bell rings after you strike it, not before you strike it. This means that the function that describes the response of a bell to being struck must be zero until the time that the bell is struck. Consider a particle of mass moving ... WebOur approach is based on space-domain Kramers-Kronig relations that transform the spatial variation in intensity to the spatial variation in phase. We demonstrate two-dimensional holographic imaging and three-dimensional refractive index tomography of microscopic objects and biological specimens from intensity images measured with an …

The Kramers … WebThe Kramers–Kronig relations (KKR) are relations between the real and imaginary part of the dielectric function. They are of a general nature and are based on the properties of a complex, analytical response function f (ω) = f 1 (ω) + if 2 (ω) fulfilling the following conditions:1 · The poles of f (ω) are below the real axis.
