Abstract: Abstract Bessel illumination is an established method in optical imaging and manipulation to achieve an extended depth of field without compromising the lateral resolution. When broadband or multicolour imaging is required, wavelength-dependent changes in the… read more here.

Abstract: Abstract A novel approach to interrogate a fiber grating sensor based on dispersive Fourier transformation method is proposed and simulated. In the system, two chirped fiber Bragg gratings (CFBG), with one used as a reference… read more here.

Abstract: This paper considers the non-Hermitian Zakharov-Shabat (ZS) scattering problem which forms the basis for defining the SU(2) nonlinear Fourier transformation (NFT). The theoretical underpinnings of this generalization of the conventional Fourier transformation are quite well… read more here.
