The goal of this project is to develop, demonstrate, and deliver to NASA an innovative, portable, and power efficient Remote UV Fluorescence Lifetime Spectrometer (RUVPhaseTM) for the in-situ robotic or manned crew planetary scientific exploration and investigation of surface and subsurface geophysical terrain. The RUVPhaseTM system is based on the integration of ROI's leading technologies: 1) frequency domain fluorescence lifetime-resolved imaging spectroscopy using time gated "phase-locked" detection, 2) steady-state fluorescence miniature spectrometer, and 3) remote fiber optic laser induced UV fluorescence detection. The RUVPhaseTM technology addresses the problem of developing a compact, energy efficient, fast detection, and highly sensitive UV Fluorescence Lifetime Spectrometer to remotely detect and measure fluorescence signals from geophysical lunar materials such as minerals and organic species that exhibit characteristic fluorescence signatures in the UV-Visible spectrum with relatively low fluorescence quantum efficiencies. The innovativeness of the miniature RUVPhaseTM system will support a large variety of NASA terrestrial and space scientific discovery applications for chemical and biological materials identification and characterization as well as in the commercial market for medical and biological applications, chemicals and pharmaceuticals, environmental science, and defense and homeland security applications.

The RUVPhaseTM technology products are expected to find wide applications for NASA and in military, government, and civilian remote fluorescence sensing applications. The specific commercial market for such innovative spectrometers with fast growing emerging markets include the biomedical, pharmaceutical, chemical and petro-chemical, environmental, and geophysical fluorescence instrumentation market. Explosive markets ROI currently addresses with the RUVPhaseTM technology include fluorescence DNA sequencing, remote fluorescence monitoring of chemical and biological agents in military and homeland security applications, fluorescence monitoring of vegetation and marine life stress affected by the oil spill in the Gulf of Mexico, and fluorescence cryogenic gas leak sensing. Technology innovation is the driving force that has opens spectroscopic applications to new markets. These new markets and applications ins turn are driven by new instrument designs that are compact, lower cost, more functionality, and better performance.

The RUVPhaseTM system will support a large variety of NASA terrestrial and space scientific applications for inorganic, organic, and biological materials identification and characterization. NASA has a need for advanced, lightweight, and power efficient scientific instrumentation that enable the remote or manned operated planetary scientific exploration of subsurface and surface geophysical measurements. The Lunar surface and subsurface is composed of a variety of mineral species that absorb light of certain wavelengths and emits light of other wavelengths. These emissions and absorptions create a "spectral signature" that can be use to identify and classify the mineral composition and its genealogical history.
