摘要： A fiber optic grating sensor system is used to localize and measure the environment associated with high speed events including pressure, temperature, velocity and position. This system has the capability to provide timing and physical location markers allowing the character of a rapidly changing event to be accurately measured with specific reference to time and location of that event. The system consists of a fiber grating sensor assembly that may consist of a fiber grating array or chirped fiber grating. Markers are put in place by using short fiber gratings that either occupies a different spatial or spectral space so that environmental measurements can be accurately related to time and space. The reflective spectra can be interpreted rapidly through the use of spectral filters, the disappearance of the fiber grating assembly due to an energetic event or arrays of high speed detectors supported by dispersive elements.
