high-speed cameras

Dear Roy,

Drinking from a fire hose is expensive.

We have built 7 HFR cameras for White Sands Missile Range with the
following characteristics:

* Thinned, back illuminated 1024 x 1024 pixel 32 port Split-FT CCD with on
chip CDS
* 100% optical fill factor
* Blooming control
* Low transfer smear
* 150 fps full resolution, 300 fps with 2:1 vertical binning
* Variable frame rate from 30 to 300 fps
* 32 (12 bit) ADCs
* 24 fiber-optic cables deliver 12 bit digital video to a proprietary video
processor
* 1.9 Gb/sec sustained video data rate, 3.8 Gb/sec capability
* Video also re-formatted for RS-170 display at 512 x 480 pixels for all
frame rates
