Abstract:

A method and apparatus for extracting the vector optical properties of biological samples with micron-scale resolution in three dimensions, using polarization-sensitive optical coherence tomography (PS-OCT). The method measures net retardance, net fast axis, and reflectivity. Polarization sensing is accomplished by illuminating the sample with at least three separate polarization states, using consecutive acquisitions of the same pixel, A-scan, or B-scan. The method can be implemented using non-polarization-maintaining fiber and a single detector. This PS-OCT method reported measures fast axis explicitly. In a calibration test of the system, net retardance was measured with an average error of 7. 5 (standard deviation 2. 2) over the retardance range 0 to 180, and fast axis with average error of 4.

Abstract:

A system for managing litigation documents including a computer-readable medium having a litigation management application. The application has computer-executable instructions for managing documents. The system includes a server that executes the instructions for managing documents on the computer-readable medium. The system has a database containing document information. The database is arranged with the server such that the server can access and modify document information in the database. The application includes a first documents tab that receives inputs from a first user to upload documents to the database for display in the first documents tab. The application has a second documents tab that receives inputs from a second user. The application generates a notification for delivery to the second user when the first user uploads a document to the database. The application can display the document in the second documents tab when the first user uploads the document to the database.
