Abstract

An apparatus for identifying a concentration of a specific material within a first material includes an input for receiving a signal after the signal passes through the first material. The signal has at least one orthogonal function therein and the at least one orthogonal function comprises at least one of an orbital angular momentum function or a Laguerre-Gaussian function. A detector detects the at least one orthogonal function within the signal, determines the concentration of the specific material within the first material based upon the detected at least one orthogonal function and generates an indication responsive to the determination. An output provides for an output of the generated indication.
