A high speed imaging system for research on ultrafast, repeated-use materials and systems
Abstract
The smallest, fastest, repeated-use movements on the planet are generated by organisms. Such extreme, non-destructive performance is achieved through tuned, dynamic interactions of multiple integrated components, specifically through the loading of energy into elastic deformation of materials, control of energy loading and release through latch mechanisms, and the generation of extreme accelerations powered by elastically recoiling materials. At sub-millisecond and sub-millimeter scales, the dynamics of energy flow and control of these systems have been invisible or just barely resolved even with state-ofthe- art high speed imaging. As such, engineers striving to match the performance of these fast systems and scientists attempting to experimentally solve their ultrafast dynamics are regularly thwarted by the ÒsimpleÓ process of visualization. Rigorous analysis, modeling and synthesis require sufficiently resolved temporal and spatial dynamics. Effective visualization of whole system output and component interactions is feasible with the proposed high speed imaging system (Specialised Imaging Kirana-01M Ultra High Speed Video Camera) which films up to 1 million frames per second with a resolution of 924x768 pixels. These capabilities more than triple the usable frame rate and pixel resolution of the high speed imaging systems currently in use. This technological advance would transform the experimental, modeling, and synthesis work of two ARO-sponsored MURI teams examining the control pathways and integrated tuning of dynamic components of impulsive biological and synthetic systems and materials. This imaging technology would transform other research initiatives establishing the outer extremes of repeatable ultrafast movement, materials synthesis and energetics. The technology would also enhance ongoing educational initiatives in biomechanics and bio-inspired systems.
