METHOD AND DEVICE FOR RECORDING OPTICAL NEAR FIELD INTERACTION SIGNALS

摘要

Methods of recording optical near field interaction signals in the infra red region are disclosed, comprising the following steps: illumination of a combination of objects with at least two objects (1, 2) using infra-red irradiation, such that an infra-red near field coupling is generated between the objects (1, 2) and recording of the scattered light emanating from the object combination which has a component (s) which is modified by the near field coupling. At least one of said objects (1, 2) comprises a polar material, having, at least partly, a polar solid structure and, on illumination, at least one phonon resonance is stimulated in at least one of the objects (1, 2) with the polar material, by means of which the modified portion (s) of the scattered light is amplified. Uses for the method in measurement technology, data storage technology and optical signal processing are also disclosed.
