溶液的在线浓度测量在许多工业过程中作为质量生产控制的手段受到极大关注，以便测量有害溶液或操作员无法达到的溶液的浓度。本文介绍了一种光纤长周期光栅（LPG），用于测量氯化钠、氯化钙和乙二醇水溶液的折射率。分辨率值与阿贝折射计提供的值相当或甚至更好，阿贝折射计通常用于这些类型的测量，获得（C）2001 Elsevier Science B.V.保留所有权利。
The on-line concentration measurement of solutions is of great interest in many industrial processes as a means of quality production control, in order to measure concentrations of harmful solutions or solutions that cannot be reached by the operator. An optical fiber long-period,orating (LPG), tested for the refractometry of sodium chloride, calcium chloride and ethylene glycol aqueous solutions, is presented. Resolution values comparable to or even better than those offered by an Abbe refractometer, that is typically used in these types of measurements, an obtained (C) 2001 Elsevier Science B.V.
