Temporal Talbot effect in free space [PDF]
Optics Letters, 2021 The temporal Talbot effect refers to the periodic revivals of a pulse train propagating in a dispersive medium and is a temporal analog of the spatial Talbot effect with group-velocity dispersion in time replacing diffraction in space. Because of typically large temporal Talbot lengths, this effect has been observed to date in only single-mode fibers ...

, 2021 The Talbot effect, also referred to as self-imaging or lensless imaging, was originally discovered in the 1830's by Henry Fox Talbot. Over the years, various investigators have found different aspects of this phenomenon, and a theory of the Talbot effect capable of explaining the various observations based on the classical theory of diffraction has ...

Fractional nonparaxial accelerating Talbot effect [PDF]
Optics Letters, 2016 We demonstrate the fractional Talbot effect of nonparaxial accelerating beams, theoretically and numerically. It is based on the interference of nonparaxial accelerating solutions of the Helmholtz equation in two dimensions. The effect originates from the interfering lobes of a superposition of the solutions that accelerate along concentric ...

An experimental study of the plasmonic Talbot effect
Optics Express, 2009 The Talbot effect of the surface plasmon polaritons (SPPs) using SPP launching gratings is studied experimentally. Talbot carpets are obtained and the Talbot distance is given when the paraxial approximation is not satisfied. Multi-layer and multi-level-phase launching gratings are designed to enhance the intensities of the amplitude-modulated revivals.

Temporal Talbot effect: from a quasi-linear Talbot carpet to soliton crystals and Talbot solitons [PDF]
Optics LettersThe temporal Talbot effect refers to the periodic self-imaging of pulse trains in optical fibers. The connection between the linear and nonlinear temporal Talbot effect is still not fully understood. To address this challenge, we use the soliton radiation beat analysis (SRBA) and numerically investigate the evolution of a phase-modulated continuous ...

History of the steel industry in the Port Talbot Area 1900-1988 [PDF]
, 2011 This thesis examines the history of steelmaking at Port Talbot in South Wales from the start of modern steelmaking in 1902 to 1988. Although the British steel industry has been studied at national level, few studies have looked at company level and ...

Physical Review Letters, 2020 A freely propagating optical field having a periodic transverse spatial profile undergoes periodic axial revivals - a well-known phenomenon known as the Talbot effect or self-imaging. We show here that introducing tight spatio-temporal spectral correlations into an ultrafast pulsed optical field with a periodic transverse spatial profile eliminates all

Reconstruction of Talbot self-image using Fourier ptychographic microscopy
Alexandria Engineering Journal, 2022 Fourier ptychographic microscopy (FPM) is used to merge a sequence of low-resolution Talbot images into a high-resolution image with a large field of view such that both integer and fractional Talbot lengths are clearly resolved. It is also revealed that
