Paper Abstract

Possible approach to monitoring of the thermal-mediated cartilage reshaping can be based on application of the polarization-sensitive speckle-correlometry. This method deals with correlation analysis of spatial-temporal fluctuations of laser light scattered by modified tissue under the condition of polarization discrimination of detected speckle-modulated scattered optical signals. In the presented paper, various techniques of correlation analysis of polarization-dependent speckle intensity fluctuations are discussed. Experimental results obtained for tissue phantoms and partially denaturated in-vitro tissue samples are presented. The sensitivity of the polarization-dependent correlation functions of the intensity fluctuations of scattered light to the content of denaturated tissue fraction ("amorphous phase") is demonstrated.
