چکیده
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.

In this study, a new numerical method is introduced to obtain the exact shape of output pulse in the chalcogenide fiber Bragg grating (FBG). A Gaussian pulse shape with 173 ps width is used as an input pulse for lunching to a 6.6 mm nonlinear FBG. Because of bistable and hysteresis nature of nonlinear FBG the time sequence of each portion of pulse is affected the shape of output pulse. So we di...
