Paper Abstract

This paper is dedicated to THz pulse holography with reference beam, opposite to our last year report on THz pulse holography without reference beam1. With reference source, we can use not only wavefront inversion modelling for reconstruction, but also reconstruction by shorter wavelength radiation that is much easier to be viewed. Using almost the same setup as in THz holography with reference beam, after digital registration we can reproduce hologram at the desired THz wavelength scaled to the desired reconstruction wavelength, then, we use standard scheme for reconstruction. Taking into account time needed for computational reconstruction, the new approach looks promising especially for practical purposes. A comparison between reconstruction techniques related to resolution and noise dependency is given.
