一、至少用两根光纤并借助于一全息透镜进行耦合的装置本专利介绍了一种用光纤并借助于全息透镜耦合光束的一种装置。全息透镜用一根单模光纤和一束参考光束所形成的干涉光波制成。在全息透镜被形成之后,单模光纤就可被多模光纤代替。本专利主要介绍的是一种与光纤有关的装置。(摘译自Applied Optics Vol 23No.13 1 July 1984。) 二、非垂直观察的光学系统为了防止梯形失真和畸变,本专利介绍了
I. Device for coupling with at least two optical fibers and by means of a holographic lens This patent describes a device which uses optical fibers and couples the optical beams by means of holographic lenses. Holographic lenses are made of interference light waves formed by a single-mode fiber and a reference beam. After the holographic lens is formed, the single mode fiber can be replaced with a multimode fiber. This patent mainly introduces an optical fiber-related devices. (Translated from Applied Optics Vol 23No.13 1 July 1984.) Second, non-vertical optical system to observe the trapezoidal distortion and distortion prevention, this patent describes
