The information capacity of an image in the atmosphere, ocean, or biological media does not grow indefinitely with increasing light power but has well defined limits. Here, the exact effects of the propagation of light in ...

It is possible to devise an experiment in which the local vorticity of a flow can be estimated by probing the fluid with Laguerre–Gauss (LG) beams, i.e., optical beams that show an azimuthal phase variation that is the ...

A new method to overcome some limitations in the simulation of the propagation of waves originating from a point source through a very long path in a turbulent medium is presented. Existing propagation simulation algorithms ...

When a light beam with a transverse spatially varying phase is considered for optical remote sensing, in addition to the usual longitudinal Doppler frequency shift of the returned signal induced by the motion of the scatter ...

In this work we will review some of the novel applications, recently proposed, where the use of structured light has played a crucial role. First, in the field of laser remote sensing, we discuss about a technique that ...

There exist optimal modes for free-space spatial-mode multiplexing with minimum degradation, under a realistic assumption that a transmitter knows the statistics of propagated fields. Using these modes as transmit and ...

The performances of satellite-to-ground downlink optical communications over Gamma–Gamma distributed turbulence are studied for a multiple-aperture receiver system. Equal gain-combining (EGC) and selection-combining (SC) ...

Structured light refers to the generation and application of custom light fields. As the tools and technology to create and detect structured light have evolved, steadily the applications have begun to emerge. This roadmap ...

A simple optical system for the self-homodyne detection of the orbital angular momentum (OAM) carried by optical beams is introduced. We propose two different schemes based on the use of optical hybrids, which could detect ...
