Helico-conical optical beams self-heal.
An optical beam is said to be self-healing when, distorted by an obstacle, the beam corrects itself upon propagation. In this Letter we show, through experiments supported by numerical simulations, that Helico-conical optical beams self-heal. We observe the strong resilience of these beams with different types of obstructions, and relate this to the characteristics of their transverse energy flow.
متن کاملExact Closed-Form Solution for Vibration Analysis of Truncated Conical and Tapered Beams Carrying Multiple Concentrated Masses
In this paper, an exact closed-form solution is presented for free vibration analysis of Euler-Bernoulli conical and tapered beams carrying any desired number of attached masses. The concentrated masses are modeled by Dirac’s delta functions which creates no need for implementation of compatibility conditions. The proposed technique explicitly provides frequency equation and corresponding mode ...

متن کاملInterferometric array illuminator using polarized beams
A two -dimensional non-observable square array illuminator using four polarized beams from two interferometers in tandem is reported. The array pattern could be scanned over large longitudinal distances without loss of distortion. Fringe visibility of interferograms has been studied as a function of polarization of the interfering beams. The expressions for the array patterns and the fringe vis...
متن کاملInternal conical refraction of light beams in biaxial gyrotropic crystals
Internal conical refraction in biaxial gyrotropic crystals has been studied theoretically. A special case of Gaussian beam conical refraction has been considered comprehensively. The results of numerical simulation agree well with the available experimental data. 2002 Elsevier Science B.V. All rights reserved. PACS: 42.25.Bs; 42.25.Lc; 42.25.Fx; 78.20.Ek; 78.20.Fm
