Popis: A high-speed digital imaging system employing electronic controls and standard optical elements has been developed. A cavity-dumped argon laser is used to provide very short duration monochromatic light pulses with short interpulse times, while an acousto-optic deflector provides spatial separation of each image. Electronic solid-state imaging is accomplished with charge injection device cameras. Full frame images (512 × 512 pixels) of the actual light intensity variations in the imaged object are digitally recorded to a resolution of 256 gray levels using a frame grabber and a host computer. This system has applications m the study of high-speed phenomena, such as dynamic fracture, impact mechanics and fluid flow.
