Abstract
The versatility of the LLNL developed 75-mm format high-speed electro-optic camera has been improved by the addition of a microchannel plate image intensifier to the electronic image converter, and by the replacement of the discreet objective lens with a commercially available zoom lens. The image intensifier can be operated at a gain of up to 10,000. This allows the use of nanosecond or subnanosecond laser strobe light pulses for object illumination thus improving the time resolution of the camera by at least an order of magnitude. The discreet objective lens of the camera has been replaced with a fast (f/4) 200-400 mm zoom lens that when coupled with a quick-connect telephoto adapter (either 1.4x or 2.0x) allows the camera to operate at any focal length from 200 to 800 mm. This permits variable magnification of the object without having to move the camera and without any degradation of dynamic spatial resolution or significant loss of light gathering ability.
