随着光纤（FO）传感技术的快速发展，商用FO加速度计刚刚进入市场。基于光纤布拉格光栅（FBG）技术的解决方案在满足FO加速度计的市场需求方面具有更大的潜力，这在一定程度上是由FO传感器的一些有价值的特性所驱动的，例如对电磁场的抗扰性以及遥感和大规模多路复用功能。本文介绍了一种温度补偿型光纤光栅加速度计的设计和测试结果。文中还介绍了为该加速度计专门设计的信号调理单元。加速度计尺寸为21 x 21 x 13 mm。采用模块化设计，可组合三个单元测量三轴加速度。
Following the fast developments that have been taking place in fiber-optic (FO) sensing technology, commercial FO accelerometers are just now reaching the market. Solutions based on Fiber Bragg grating (FBG) technology are the ones that show the greater potential of responding to market demands for FO accelerometers, driven, in part, by some of the valuable characteristics of FO sensors, such as immunity to electromagnetic fields as well as remote sensing and large multiplexing capabilities. In this paper, we present the design and test results of a temperature-compensated FBG accelerometer. The signal conditioning unit, specially designed to this accelerometer is also presented. Accelerometer dimensions are 21 x 21 x 13 mm. Design is modular, such that three units can be combined to measure tri-axial acceleration.
