1. A method of determining an attribute of a target, comprising:

  • generating probe radiation;

    applying at least a portion of said probe radiation to said target to generate back-scattered radiation;

    generating reference radiation;

    combining said back-scattered radiation and said reference radiation to produce an interference signal;

    detecting said interference signal by means of a detector;

    extracting concurrent information from said detected interference signal;

    correlating said extracted concurrent information with data from a data bank stored in memory to generate correlation data; and

    processing said correlation data to determine said attribute of said target.
