Optical Design of Laser Beam Shaping Systems
An overview of the history and current practices of laser beam shaping is presented. When diffraction effects are not important, geometrical methods for laser beam shaping (ray tracing, conservation of energy within a bundle of rays, and the constant optical path length condition) can be used to determine system configurations, including aspheric elements and spherical-surface GRIN lenses, whic...
متن کاملOptical metasurfaces for polarization-controlled beam shaping.
We have developed multifunctional optical beam shapers based on plasmonic metasurfaces. The metasurfaces are composed of subwavelength-spaced polarization- and wavelength-selective optical nanoantennas that allow encoding several beam shapers on a single element. We demonstrate numerically and experimentally beam shapers that can be used to switch between arbitrary beam shapes. We specifically ...
متن کاملReal time modulable multifocality through annular optical elements.
We present and analyze new multifocal optical elements based on an annular distribution of the transmittance. These elements provide selectable number of foci and can be designed to work between two fixed positions or even to provide extended focal depth. The energy of the foci can be modulated through a single parameter that controls the area of each ring. In our study we analyze the quality o...
متن کاملReal-time hyperspectral imaging with volume holographic optical elements
We report a novel hyperspectral optical sensor capable of providing image information with four degrees of freedom (4D), i.e. volumetric spatial information and spectral information simultaneously, in real time. The imaging principle is based on the diffraction properties of volume holographic optical elements designed as spatial-spectral filters. The 4D imager can be configured to image object...
متن کاملTime-domain Beam Shaping of Pulsed Arrays
Pulsed arrays are becoming popular in new Ultra-wideband applications to enhance the robustness of transmitted and received signals in complex environments and to identify the angle of arrival of multiple echoes. A global synthesis technique is here proposed to shape the array field in accordance to a given angle-time mask. The synthesis problem is cast as the inverse Radon transform of a desir...
