High Speed Video Data Acquisition System

A high speed video data acquisition system was developed for aero-optical experiments conducted in a wind tunnel. The system acquired two dimensional video data at 370 frames per second. Each frame was an array of 128 by 128 pixels, each pixel digitized to six bits of intensity resolution. This produced a data rate of 8M bytes per second. To minimize the cost, off the shelf hardware was used, with the exception of a custom computer interface board. The design and operation of and future improvements to this system are discussed in this paper.
