Abstract

In this work, terahertz images have been simulated from X-ray images. For this aim the terahertz raster scanning process is modeled by a two dimensional convolution of the modelled THz beam and the X-ray image. The mathematical model of the terahertz beam has been modeled by a Gaussian function. The variables in this function are frequency of the beam, lateral location and absorption coefficient of the object. The accuracy of the proposed approach has been verified by comparing the results with the actual terahertz images.
