Cp. Burger et al., A HIGH-SPEED DIGITAL IMAGING-SYSTEM FOR RECORDING NONREPETITIVE TRANSIENT EVENTS, International journal of solids and structures, 32(17-18), 1995, pp. 2813
A high-speed digital imaging system employing electronic controls and
standard optical elements has been developed. A cavity-dumped argon La
ser 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 a
ccomplished with charge injection device cameras. Full frame images (5
12 x 512 pixels) of the actual light intensity variations in the image
d object are digitally recorded to a resolution of 256 gray levels usi
ng a frame grabber and a host computer. This system has applications i
n the study of high-speed phenomena, such as dynamic fracture, impact
mechanics and fluid flow.
