Abstract:
1. A method of identifying potential disease within a particular tissue of a plant or animal comprising the steps of: introducing into the tissue at least one input pulse of radiation through at least one large-core microstructured multimode optical fiber operating in a single-mode regime, wherein the at least one input pulse causes nonlinear activation of the tissue, and wherein the tissue emits at least one nonlinear signal in response to nonlinear activation; comparing said at least one nonlinear signal produced by said introducing to at least one nonlinear signal emitted by healthy tissue of the particular plant or animal under the same conditions used to carry out said introducing; and identifying the particular tissue of a plant or animal where the at least one nonlinear signal produced by said introducing differs from said at least one nonlinear signal emitted by said healthy tissue of the particular plant or animal under the same conditions used to carry out said introducing, as potentially diseased, wherein said at least one large-core microstructured multimode optical fiber has a numerical aperture of equal to or greater than 0.2.
