It commonly describes the propagation of Gaussian beams where the beam width is comparable to the wavelength. This is in contrast to geometrical optics, where the wavelength is small compared to the relevant length scales. Quasioptics is so named because it represents an intermediate regime between conventional optics and electronics, and is often relevant to the description of signals in the far-infrared or terahertz region of the electromagnetic spectrum. It represents a simplified version of the more rigorous treatment of physical optics. == See also == *Optoelectronics 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Quasioptics」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
