摘要：

This paper presents a comprehensive theory for cohesive mathematical modeling and simulation of THz imaging systems. For mathematical modeling of the point spread function (PSF), system and transmission variables such as spectrum, absorption coefficient, beam divergence, and depth of focus are incorporated into the Gaussian beam distribution. The raster scanning process is mathematically modeled as the convolution of the object function and the PSF. Simulated transmission THz images are achieved as a result. The simulated THz images, compared to the experimental THz images, show great accuracy in terms of the location of the details and structural similarity.
