Latest Patents: Among his latest patents, Libbey has developed the "Method for Phase Resolved Heterodyne Shearographic Measurements." This invention introduces a phase-resolved heterodyne shearing interferometer, allowing for high-rate, whole-field observations of transient surface motion. It utilizes polarization multiplexing and multiple carrier frequencies to separate elements of a shearing Mach-Zehnder interferometer. His innovative post-processing routines recombine the segments to provide quantitative relative phase changes, enabling the creation of variable shear, phase-resolved shearographic fringe patterns without temporal or spatial phase shifting.

Another notable patent is the "Apparatus for a Dynamic Multi-Axis Heterodyne Interferometric Vibrometer." This device allows for the observation of five degrees of dynamic freedom using a single illumination source. The system employs polarization and frequency multiplexing to observe and separate image and Fourier planes after coherent illumination scatters from a dynamic surface. It also features unique optical configurations that help generate simultaneous image and Fourier planes on a focal plane array. The technology captures critical data about an object's in-plane translation, out-of-plane rotation, and out-of-plane displacement.
