The sensor’s dynamic characteristic is very important. Now, however, sensor is designed according to static performance indexes, and is evaluated on the basis of static calibration. Therefore, the dynamic performance of sensor does not satisfy practical demands often in application. At this time, it is impossible to change the sensor’s structural parameters because it involves the static specifications and is limited by technique. The compensating method must be adopted to improve sensor’s dynamic The sensor’s dynamic characteristic is very important.
