Abstract

Under Phase-I OKSI will demonstrate at the AEDC G-Range, using low cost off the shelf hardware, a photographic technique that creates double-exposure freeze-motion images of the projectile in a single frame. The two images will be separated by a time delay from microseconds to a few milliseconds, depending on the actual projectile velocity. This demonstration will take place down range closer to the target section of the facility. The images will be used to extract the full projectile orientation in pitch (angle of attack) and yaw, and the speed will be extracted from the displacement between the double images. In addition, using OKSI's AVNIR high speed imaging spectrometer, OKSI will perform during Phase-I spectral measurements of the radiation in the blast zone (muzzle exit) of the facility. The data will establish whether certain spectral bands can be isolated for use in similar high speed photography. If not, a modified imaging system will be developed for the blast zone. Analysis and experimental data developed under Phase-I will be used to design and build a fully functional prototype system that will be delivered to AEDC under Phase-II. The proposed system includes two backscattering laser trigger stations upstream of the imaging station that provide redundant measure of projectile velocity and used to trigger each of the two flashlamp pulses in the imaging station.
