GHz - Rate Imaging System for Study of High - Speed Combustion, Detonations, Explosions, Flows, and Plasmas
Abstract
We propose to acquire an ultra-high-speed intensified camera system that is capable of obtaining 16 image frames with megapixel resolution at rates up to 1 billion frames per second (1 ns between images). This gigahertz framing camera will allow us to provide unprecedented measurement of the extremely fast processes occurring in numerous systems of relevance to the Air Force and Department of Defense, including supersonic combustion, detonations, explosions, plasmas, material deformation, and high-speed flows. Measurement techniques enabled by this camera include ultra-fast emissions spectroscopy, optical flow velocimetry, schlieren imaging (including background oriented schlieren tomography), shadowgraph imaging, holography, time-resolved laser induced incandescence, laser induced breakdown spectroscopy, and digital image correlation. Gigahertz-rate imaging systems have undergone significant progress in recent years. It currently is possible to capture 16 frames at up to a billion frames per second (0 ns minimum frame offset time with 1 ns minimum increment size, 3 ns We propose to acquire an ultra-high-speed intensified camera system that is capable of obtaining 16 image frames with megapixel resolution at rates up to 1 billion frames per second (1 ns between images).
