Abstract A high‐resolution, multi‐frame, image‐converter camera developed for high speed photography is applied to study the dynamic behavior of shear‐formed shaped‐charge liners. Grid lines applied to the inner liner surface allow the precise quantification of liner collapse, early jet formation, and jet development for comparison with two‐dimensional hydrocode simulations. The technique affords the first direct measurement of the angular velocity of jets formed from shear‐formed shaped‐charge liners.
