Light at the output of the sample contains a contribution from the standard scattered photons, and another one from light that has crossed the ultrasonic volume, that is frequency shifted by the ultrasound wave. These so-called tagged-photons are carrying the acousto-optical contrast information, as the number of tagged photon is dependent on the number of photon transmitted by the interaction area, and thus to the local absorption of the media. A drawback of this technique comes from the speckle structure of the transmitted waves caused by the multiple-scattering process occurring in the biological tissue, so that the extraction of the useful information generally requires an interferometric detection with a high optical etendue","PeriodicalId":354643,"journal":{"name":"CLEO/Europe. 2005 Conference on Lasers and Electro-Optics Europe, 2005.","volume":"469 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-06-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116788620","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
