WebFeb 1, 2007 · Contrary to the incoherent spontaneous Raman process, CARS is a third-order nonlinear optical process in which a pump excitation field at frequency ω P and a Stokes excitation field at frequency ω S are mixed in a sample to generate an anti-Stokes signal field at frequency ω AS = 2 ω P-ω S (Fig. 1 (c)). The anti-Stokes signal is generated … WebSep 23, 2013 · Intravoxel incoherent motion (IVIM) imaging is a method proposed by Le Bihan et al 9 to separate the signal arising from a diffusion sequence such as the Stejskal-Tanner sequence 10 into a vascular and a nonvascular component. It assumes an isotropic and sufficiently randomly laid microvasculature network, so that water molecules in the …
WebSep 30, 2024 · In this paper, we aim to develop a new subspace-based method for Direction Of Arrival estimation (direction-finding) using coherent wide band (WB) or ultra-wide band (UWB) signals. Subspace-based methods are well-established in the incoherent narrow band signals context; nevertheless, only a few of them are adapted to the case of WB or UWB … WebMar 15, 2024 · Abstract: Weak optical signal processing based on nonlinear effects offers new approaches for imaging through scattering media.
