Research Interests

Dr. Cha’s research interests cover a broad scope of multidisciplinary practices involving the latest advances in optical diagnostic techniques. These include quantitative/qualitative visualization of fluid and heat transfer fields, combustion/emission nondestructive testing. Not only is he in a unique position to develop these cutting-edge techniques, but to also apply them in characterizing various mechanical phenomena. Current activities are concentrated on laser experimentation and instrumentation for fluid flow, heat/mass transfer,and combustion three-dimensional multi-component velocimetry; holography/interferometry-based techniques; light scattering, spectroscopy, radiative heat transfer and laser machining/processing. Photomechanics including nondestructive evaluation. Numerical investigation of experimental phenomena. The tasks require investigations in computational tomography, digital image processing, signal processing, and optics as well as appropriate hardware developments.
