摘要：
The effect of enhancement of image contrast and spatial resolution without the loss of the spectral composition of the radiation under investigation has been experimentally demonstrated for a terahertz far-field imaging system. The result has been obtained by using a confocal aperture placed in the intermediate-focus region of the optical system. The result is a fundamental advance towards the achievement of subwavelength resolution and the contrast of microscopy systems in the terahertz spectral range.
