| Abstract: | This article describes a group of optical methods for studying the explosion of shaped charges, including modifications of
established methods (slit photorecording, the luminous points method, laser probing) and two new methods — measurement of
wave velocities with transducers based on optical fibers and laser visualization of the shaped-charge jet. Optical methods
are used to study such jets under laboratory conditions. Characteristic distortions of the symmetry of the detonation front
and their effect on the jet are discussed, the probable character of breakup of the jet is established, and the distribution
of the jet particles with respect to size is determined along with the maximum values of average limiting tension for copper.
