Paper Abstract

We are exploring new applications of the technology of energy deposition and dynamic response. Early studies involved analytical solutions of the coupled thermal and elastic response of materials to pulsed energy deposition. Experiments designed to test the theory led to determinations of thermal pressure coefficients for a variety of materials and an understanding of the effects of the time dependence of the energy source on dynamic response. Subsequent experiments at higher deposited energies required analysis by an energy deposition-wave propagation code to explain the observed elastic-plastic behavior. Instrumentation included laser interferometry and holographic interferometry for multi- dimensional response. A possible application of this technology to Biomedical Science is a technique to measure ion transport in biological material. It requires a combination of holographic interferometry and spectroscopy, namely, Resonant Holographic Interferometry Spectroscopy (RHIS). The technique involves the absorption and refraction of light near absorption lines. Stress waves arising from the absorbed light can be assessed with the energy deposition-wave propagation code. Such calculations will require the inclusion of appropriate biomaterial properties.
