Abstract
An optical technique is carried out in our lab which uses velocity interferometers to measure the shear-wave velocity on the surface of a sample. By the planar impact on a one stage gas gun with 57 mm diameter and the anisotropy of Y-cut quartz, a combining pressure-shear loading in Ly-12 Al bonded to the rear surface of Y-cut quartz is generated. Two velocity interferometers were employed to measure simultaneously the longitudinal and transverse velocity histories on the free surface. An optical alignment method which uses laser to adjust the parallelism of the impactor and the target is also described and a measure to overcome the low laser power used in our experiments is also put forward in this paper.
