Here, we show a method to measure the topological charge of a partially coherent ELG beam. We find that the number of ring dislocations in the far-field complex degree of coherence is equal to the topological charge |l| of a partially coherent ELG beam, and which is confirmed experimentally. Our results will be useful for applications using partially coherent ELG beams. © 2018 Optical Society of America under the terms of the OSA Open Access Publishing Agreement | Source Title: | Optics Express | URI: | https://scholarbank.nus.edu.sg/handle/10635/210849 | ISSN: | 10944087 | DOI: | 10.1364/OE.26.033035 | Rights: | Attribution 4.0 International |
