The exchange of oxygen at the surface of open waters under wind forcing
… 4. Consideration of previously unidentified optical distortions in LIF imagery due to non-linear effects is presented that is critical for robust LIF data processing and experimental design. A formal mathematical description of optical distortions has been developed and presented.

Development of an Internal Camera-Based Volume Determination System for Triaxial Testing
… cumbersome corrections required to account for optical distortions due to 1) the refraction of light at the confining fluid-cell wall-atmosphere interfaces, 2) the curvature of the cylindrical cell wall, and 3) the deformation of the cell wall induced by changes in cell pressure. Digital images …

Machine Vision for Improved Human-Robot Cooperation in Adverse Underwater Conditions
… are exacerbated by a host of non-linear image distortions caused by the vulnerabilities of underwater light propagation (e.g., wavelength-dependent attenuation, absorption, and scattering). In this dissertation, we present a set of novel and improved visual perception solutions to address these …

Design and Performance of Cold Bent Glass
… limits are exceeded and could degrade the optical quality of the glass. An evaluation procedure is also formulated to set limits and aid designers/manufacturers to predict the mechanical response and the optical quality of the glass. Cold bent glass is subjected to permanent bending …
