Description
Summary:A stereo camera system has been developed for use with the laser-driven MiniFlyer apparatus. The objective of the stereo camera is to determine the three-dimensional reconstruction of the surface of a flyer plate in flight. The resolution of the system is designed to be 10 μm, based on the maximum blur expected due to the flyer plate motion during the exposure. Illumination of the flyer plate in flight is accomplished with a Q-switched Nd:YAG laser. A grid is projected onto the flyer plate surface to provide reference points for the reconstruction. The software algorithm used for the reconstruction utilizes a bilinear interpolation to fill in the data between the grid lines. Data for copper and titanium flyer plates are discussed.
