“Measure what is measurable, and make measurable what is not so” – Galileo.
Many of the research efforts in GALCIT are enabled by development of experimental tools to sense and measure physical phenomena in new ways. Ongoing work includes new three-dimensional, three- component image correlation techniques; laser-scattering diagnostic techniques; spectroscopic species and temperature measurements, and time-resolved interferometry for hypervelocity and reacting flows; nano-second exposure, high-framing rate imaging; laser scanning and metric analysis techniques for reconstruction of spatiotemporal instabilities in nanoscale films; dynamic Digital Image Correlation (DIC), ultra-high speed photography and thermography for static and dynamic deformation, localization and fracture in solid materials; strain measurement using Coherent Gradient Sensing (CGS) shearography, laser vibrometry and dynamic photoelasticity; in situ techniques for field measurements in the ocean and atmosphere; and data-driven, machine learning-based measurement approaches.
