PROJECT DESCRIPTION
My long-term research goal is to uncover the full potentials of fiber optic sensing technology regarding gas/vapor detection. In pursuit of this goal, the research objective of this proposal is to migrate the successful concept of cavity ring-down spectroscopic (CRDS) technique onto optical fibers enabling a real-time, fully distributed gas/vapor detection   technique, which is hereby called distributed optical spectroscopy. The fundamental knowledge of the distributed optical spectroscopy is suitable for many applications including natural gas detection, pollution monitoring, environmental management and detection of chemical/biological warfare agents.

PROJECT DESCRIPTION
Robust, embeddable, remotely-interrogated distributed sensors are highly desired for structural health monitoring (SHM) to ensure continuing safe operations of the nation’s critical infrastructures. This project aims to uncover the full potentials of a feasibility- proven, novel concept of coherent/incoherent optical frequency domain reflectometry systems  for distributed sensing in SHM. The PI will study the advantages of both systems, combine them together, and design, develop, and characterize special optical fibers (e.g., polymer optical fibers) for distributed measurement of large strain and crack detection to demonstrate the effectiveness of the new concept for SHM. Currently, the PI is focusing on steel manufacturing industry.

PROJECT DESCRIPTION
The interconnected consequences of the national energy strategy compel us to design energy systems to operate at higher temperatures to achieve greater efficiency and reduced greenhouse gas emissions. However, the availability of sensors or measurement systems becomes limited in the high temperature regimes. The PI proposes to develop a novel high- temperature tolerant ceramic coaxial cable Fabry-Perot interferometer (CCC-FPI) sensor and a unique joint time-frequency domain demodulation technique for distributed measurement of temperature or strain with high sensitivity and high spatial resolution.

PROJECT DESCRIPTION
Magnetic resonance imaging and spectroscopy (MRI/MRS) afford  inherent in vivo capabilities to diagnose early-stage cancer by specifying types of malignancies through identification and quantification of biochemical markers that indicate cancers, and by accurately measuring the boundaries of tumor volumes through image resolution on the scale of cell dimensions. However, the critical limitation to achieving accurate early-stage diagnoses of cancer tissues by MRI/MRS is sensitivity. The minimum volume of cancer cells that can be accurately analyzed for tumor type and measured to determine tumor stage is inversely related to magnetic resonance sensitivity. We seek to increase the sensitivity of MRI/MRS by three orders of magnitude, and thereby reduce the volume of the cancer cells that can be accurately diagnosed from approximately one cubic centimeter to one cubic millimeter (ca. 106 cancer cells). The fundamental basis for our approach is that proximity of the magnetic resonance detector antenna to the suspect cancer tumor maximizes sensitivity for diagnostic signals, which maximizes treatment efficacy. Indeed, our approach is to position a novel sub- surface detector antenna, based on an acupuncture needle, in direct contact with the suspect cancer tissue.
