Abstract

The effect of image contrast enhancement without the loss of the spectral composition of the radiation under investigation has been experimentally demonstrated for a terahertz far-field video 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 video systems in the terahertz spectral range.
