DURIP: A Confocal Imaging System for Ultra-Fast Three-Dimensional Transport Studies in Thermal Management Applications
Abstract
We developed a new integrated imaging system, comprised of the requested confocal microscope and high-sensitivity camera, as well as our own state-of-the-art high-speed and high-resolution cameras, to achieve diffraction-limited 3D imaging of highly transient flows. The confocal incorporates selectable pinholes to enable fast scanning, and when interfaced with a high-speed camera, can achieve capture rates up to 1000 Hz. The combination of these features offers drastic improvements to our existing imaging systems, which are limited in spatial and/or temporal resolution. The proposed system enables fundamental insights into our ongoing thermal management efforts focused on: (1) Interfacial dynamics on nanostructured surfaces, (2) Phase-change and flow through porous media, and (3) 3D velocity field measurements in microscale systems. The integrated confocal microscope system is a critical component to obtain understanding of fluid-heat-structure interactions, as well as offer design guidelines for the development of high-performance thermal management systems.
