概述近年来,随着光学通讯技术的发展,光学纤维的应用范围日趋广泛。它作为传感元件,除了用於许多物理参数的测量之外,还因其柔软性,用来制作适合各种用途的传象束。将光敏元件与光学纤维来相连,构成光纤光电藕合器、这种器件在光电藕合上等效于电荷藕合器(简称CCD器件),在传感光信息方面,可开辟应用范围,作为图象传感器。目前,以高纯度石英材料作蕊料的光学纤维已广泛用于光通讯技术中。但由於这种材料制备困难、成本高,在以传光为主要目的的应用中一般将受到限制。
In recent years, with the development of optical communication technology, the application range of optical fiber is becoming more and more widespread. It acts as a sensing element, in addition to the measurement of many physical parameters, and because of its softness, it is used to make image beams suitable for a variety of purposes. The photosensitive element is connected with the optical fiber to form an optical fiber photoelectric coupler, which is equivalent to a charge-coupled device (referred to as a CCD device) in photoelectric coupling, and can open up a range of applications in sensing optical information as a figure Like the sensor. At present, optical fibers, which are made of high-purity quartz material, have been widely used in optical communication technologies. However, due to the difficulty of preparing such materials and their high cost, they are generally limited in applications where the primary purpose of light transmission is to be achieved.
