METHOD FOR FORMING IMAGE OF OBJECTS WITH SUBDIFFRACTION RESOLUTION IN MILLIMETRIC, TERAHERTZ, INFRARED AND OPTICAL RANGES OF WAVE LENGTHS

摘要

FIELD: physics.;SUBSTANCE: method includes irradiating the forming system with the source of electromagnetic radiation, focusing the radiation by the forming system on the research object, receiving the reflected or transmitted radiation, converting the received radiation into electrical signals and forming the image of the observation object. In the radiation focusing area of the forming system, a meso-sized dielectric particle is placed, having a refractive index from 1. 2 to 1. 7 and a size of not more than the transverse dimension of the focusing area and not less than λ/2, where λ is the radiation wavelength. An area with an increased radiation intensity is created, having transverse dimensions of the order λ/3-λ/4 and a length of not more than 10λ on the outer boundary of the particle on the opposite side of the incident radiation. The research object is placed in the obtained area of increased intensity.;EFFECT: increasing the resolution.;2 dwg
