Paper Abstract

The Los Alamos National Laboratory in support of Department of Energy and Department of Defense projects is developing a continuous recording, intensified, CCD camera system having a high-frame rate and fast shutter capability. The camera frame rates can range from 1 to approximately 3500 frames per second with sub-nanosecond shuttering capability. Camera shuttering (or gating) is provided by a microchannel plate image intensifier employing a Los Alamos designed stripline geometry that incorporates impedance matching to reduce pulse reflections and dispersion. The CCD pixel array size is 512 X 512, which provides good-resolution over a relatively wide field of view. Video data readout from the CCD is through 16 parallel ports with a pixel rate of up to 75 Mpixels/s per port. Camera outputs include 16 ports of both analog video and digital video provided by 10-bit onboard digitizers. A computer controlled frame grabber is being fabricated which will record data from the digital outputs and store the data in a local memory for transfer into a non-volatile storage medium such as a removable disk drive. Salient characteristics and performance data of a prototype camera are presented and range gated imaging applications are discussed.
