准光学技术与器件是真空电子学在毫米波与远红外领域里近十余年来出现的一个新的发展方向,并逐步形成的一门新的边缘学科。对于毫米波与远红外频谱的开拓具有重要意义。本文将从基本物理思想和技术的发展来讨论有关的几个问题。在论述中,除了系统综述现有文献上的一些观点外,笔者还提出了一些自己的看法,供有关专业从事教学、科研与生产的同志们参考。
Quasi-optical technology and devices are a new development direction of vacuum electronics in the field of millimeter wave and far infrared nearly ten years, and gradually formed a new edge discipline. For millimeter wave and far-infrared spectrum development is of great significance. This article will discuss several related issues from the development of basic physical ideas and technologies. In the discussion, in addition to systematically review some of the existing literature on the point of view, the author also made some of his own views for the relevant professions engaged in teaching, research and production of comrades reference.
