The imaging is performed by interfering the light emerging from the scattering medium with a 200 fs duration pulsed local oscillator beam, and detecting the interfered light with a balanced homodyne detector. We show that the data collected by our detector can be analyzed in two ways. One method strongly suppresses the detection of scattered light emerging from the medium, leaving almost exclusively the ballistic (unscattered) component of the signal. Using the other data analysis technique, both the scattered and ballistic components of the signal are readily detected. This shows that despite the fact that coherent (homodyne) detection is used, the system can be optimized for the detection of either coherent (unscattered) or incoherent (scattered) light.","PeriodicalId":368664,"journal":{"name":"Advances in Optical Imaging and Photon Migration","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1994-05-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130126720","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}

The long range spatial and spectral correlations are analyzed and it is shown that the presence of absorption modifies qualitatively the spectral correlation function. The influence of mesoscopic fluctuations on the intensity distribution function is considered. It is shown that only for small values of intensity is the distribution function a simple exponent, as predicted by Rayleigh statistics. For larger values of intensity, the distribution function differs drastically from a simple exponential and the asymptotic behavior is a stretched exponential. Also considered is the slowing down of the diffusion in the medium with resonance scatterers.","PeriodicalId":368664,"journal":{"name":"Advances in Optical Imaging and Photon Migration","volume":"56 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129872944","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}
