Application effective de l'interferometrie holographique par double exposition a l'etude des deformations de ceramiques, dues a l'impact d'un projectile

Applications Of Coherent Optics At ISL

“…The samples investigated were plane ceramic [7] or sapphire [8] plates. The shocks were generated by projectiles launched with high velocities (from 150 m/s to 800 m /s) ( fig.…”

“…The samples investigated were plane ceramic [7] or sapphire [8] plates. In order to obtain the deformation chart of the surface opposite to the impact, doubleexposure is made prior to breaking.…”
