Computational aspects of ghost imaging diffraction in broadband terahertz range

Computational aspects of ghost imaging diffraction modelling based on broadband terahertz pulsed radiation, modulated by a random phase screen, are discussed. An image generated by transmission of an incident Gauss-Hermite beam passing through a 2D inhomogeneous thin film is the main subject of our study. The modelling is performed in both the frequency and the time domains. The quality of the reconstructed images of a set of slots of different size is analysed for various modes of the incident Gauss-Hermite beams.
