| Grating Light Reflection Spectroscopy, or GLRS, is an analytical measurement technique that functions by measuring the wavelength dependent redistribution of light that occurs when light is reflected from a grating-sample interface. Evaluation of the light reflected from the grating-sample interface allows the optical properties of a sample to be determined, and these optical properties are related to the desired parameters of interest.; The research presented in this dissertation outlines a series of experiments that have developed and explored the instrumental aspects of GLRS. The instrumentation used to perform GLRS has been pushed in three general directions: simplicity, analogy, and complexity. The direction of simplicity was achieved by developing the GLRS dip probe, which was designed to be simple, inexpensive, and user friendly. These traits allow GLRS to be used more often, by more researchers, and in more applications. The direction of analogy involves utilizing different sources of incident waves to probe the grating-sample interface. The direction of analogy allows the analogous grating reflection techniques to yield information that is analogous to the information obtained with GLRS. Finally, the direction of complexity allows new dimensions of information to be obtained. For example, one direction of complexity allows the wavelength dependence of the sample's optical properties to be determined and another direction of complexity enables the determination of the electro-optical properties of the sample. |
