Abstract

In order to analyze the polarization properties of biological tissues, we constructed a high-speed three-dimensional swept -source polarization sensitive optical coherence tomography (PS-OCT) imaging system with the axial scanning rate up to 200KHz. For automatically detecting and analyzing the polarization properties of peristaltic living tissues in real-time, an advanced measurement and control system is designed using laboratory virtual instrument technology. Based on the producer-consumer pattern, the system mainly includes the sample arm scanning galvanometer module, the interference data acquisition module, the interference data real-time processing and display module, the interference data storage module. Each module not only independently completes specific sub-functions but also interacts with others. In-vivo human finger and in-vitro pork tissue were imaged using the system. The experimental results show that the home-made system obtains 78 cross sectional B-scans per second, and can display two-dimensional OCT images and acquire threedimensional OCT data all in real-time. This robust measurement and control system has the characteristics of short design cycle, high flexibility and real-time monitoring, will significantly promote the development of PS-OCT in clinical applications.
