Abstract

Application of reflector antenna configurations in designing the optical section of terahertz imaging systems has attracted great attention during recent years. Advantages of reflective optics in comparison with refractive optics is one of the main reasons for this trend. Specular reflection in broad spectral range, no or little reflection and transmission loss, no chromatic aberration, high reliability in high power applications and even cancellation of off-axis aberrations as a result of precise optimized configuration are just some of these advantages. Moreover, utilizing novel satellite communication reflector antenna systems in an optical section of imaging systems has improved many imaging performance factors and provided a reliable platform for different imaging objectives. In this paper, we will design a Gregorian-based reflector antenna system for the optical section of terahertz imaging systems and using optical techniques, we optimize the structure for optimum imaging performance.
