Abstract

In this paper, a new approach for the fiber optic sensor system in high speed weigh-in motion (WIM) is proposed. Multiple Bragg gratings with same wavelengths and same bandwidths are used in the system. Fabry-Perot filter for the signal process, which cannot be used in the high speed measurement because of the limitation in fast operation of PZT, is excluded. Among the multiple gratings in the WIM system, the gratings under the load act as sensors and the rest of the gratings are filters in the signal process. The proposed fiber optic WIM system is tested by several actual experiments with trucks
