TL;DR: In this article, a technique for modulating the coherence and polarization of the electromagnetic field using 90o-twist liquid-crystal spatial light modulators (LC-SLMs) is proposed.

TL;DR: In this article, a new method for calculating image intensity distribution in partially coherent illumination is described, which is based on coherent mode representation of the cross-spectral density function of illumination field and allows considerable reduction of the computational effort needed for image intensity calculation in comparison with the direct method.

TL;DR: In this paper, the authors extend the concept of perfect optical vortex to the vector case and investigate its focusing properties in the high numerical aperture regime, showing that simultaneous phase encoding of orthogonal components can be realized by means of a 4 f imaging system incorporating a phase only liquid-crystal spatial light modulator whose director axis is rotated 45° with respect to the horizontal axis.

TL;DR: In this article, an improved technique for generating the perfect optical vortex is proposed, notable for the simplicity of its practical realization and the high quality of the results that is applied to an optical trapping experiment.

TL;DR: In this article, a method for introducing carrier fringes in a double-aperture common-path interferometer was presented, where the axial displacement of the first lens of the 4 f optical system involved is linearly proportional to the carrier frequency introduced in the interferogram.
