Design and Optimization of Gregorian-based Reflector Systems for THz Imaging System Optics
摘要：
反射面天线结构在太赫兹成像系统光学部分设计中的应用近年来引起了人们的广泛关注。与折射光学相比，反射光学的优势是这一趋势的主要原因之一。宽光谱范围内的镜面反射、没有或很少的反射和透射损失、没有色差、高功率应用中的高可靠性以及由于精确优化的配置而导致的离轴像差的消除仅仅是这些优点中的一些。此外，在成像系统的光学部分中使用新颖的卫星通信反射器天线系统改善了许多成像性能因素，并为不同的成像目标提供了可靠的平台。在本文中，我们将设计一个基于格雷戈里的反射器天线系统的光学部分的太赫兹成像系统，并利用光学技术，我们优化的结构，以获得最佳的成像性能。
英文摘要：
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.
