Abstract.
A method of imaging formation with
sub-diffraction angular resolution using a scanning one –
aperture terahertz telescope was offered. We
describe briefly the scheme of the telescope and the proposed algorithm for the procedure of scanning and reconstruction of
images. The simplest problem of simulation of imaging formation with sub- diffraction resolution on one-dimensional
experimental model of scanning one – aperture terahertz telescope has been put in the article. The estimation of the
possibility of improvement of angular resolution up to ~ 140 times was the result
of the simulation. Tasks which should be solved in the way of creating a one–aperture two-dimensional telescope with imaging formation
with sub- diffraction resolution have
been a prescheduled.
