1. An apparatus for identifying a concentration of a specific material within a first material, comprising:

  • an input for receiving a signal after the signal passes through the first material, the signal having at least one orthogonal function therein, the at least one orthogonal function comprised of at least one of an orbital angular momentum function or a Laguerre-Gaussian function;

    a detector for detecting the at least one orthogonal function within the signal, for determining the concentration of the specific material within the first material based upon the detected at least one orthogonal function and for generating an indication responsive to the determination; and

    an output for providing the generated indication.
