The experiment results show that this algorithm can not only strain effectively every slow changing and pulse noise, but also sharpen well the image edge simultaneously.
实验结果表明，该算法不仅可以有效滤除各种慢变化及脉冲噪声，而且在滤噪的同时能锐化目标的边缘。

Because it is hard to obtain dynamic stress equilibrium and constant strain rate in soft materials specimen during the conventional SHPB experiments, a pulse shaping technique is developed.
The shift of reflective wavelength of one FBG under external strain is translated into a change in time interval of the optical pulse from another FBG drived by a PZT plate.
