We have developed a high-speed, electro -optic camera that features a large format; eight frames; and an accompanying eight -pulse, ruby laser illuminator.This system offers greater resolution and versatility than has been previously available. The eight 75 -mm frames provide high dynamic spatial resolution (15 line pairs /mm) and time resolution (as short as 10 -ns exposure time) to record fine physical details of rapid events.Four independent two -frame (tube) cameras complete with objective optics comprise the eight -frame array. Finally, pulsed ruby laser illumination with spectral filtering allows photography in intense ambient light.

By combining the attributes ofelectro-optic shuttering and pulsedlaser illumination in alarge format camera system, we have developed a multi-frame image converter camera with a laser illuminator that produces sequentialphotographs offast phenomena with very high resolution. The combination ofthe large size image plane (75 mm), short exposure time per frame (minimum 12-15 ns), and monochromatic laser illumination provides clear, sharp, front-lit images of surfaces and shapes with no degradation by luminous air shocks or motion blur. The unique modular design ofthe camera and the laser allow for a variety ofconfigurations and applications. The current camera system produces eight independent pictures or four stereo pairs. A Q-switched ruby laser with multiple pulse capability provides individual illumination for each frame. This system has photographed a variety of fast phenomena including the first stereo sequential photographs of the initial formation and early time history of high velocity shaped-charge jets.

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.
