    Abstract: A mobile computing device that includes an image sensor may be used to detect the result of a biomolecular assay. The biomolecular assay may be performed in an optical assay medium that provides an optical output in response to light from a light source, with the optical output indicating result. A wavelength-dispersive element may be used to disperse the optical output into spatially-separated wavelength components. The mobile computing device may be positioned relative to the wavelength-dispersive element such that different wavelength components are received at different locations on the image sensor. With the mobile computing device positioned in this way, the image sensor may be used to obtain one or more images that include the separated wavelength components of the optical output. A wavelength spectrum of the optical output may be determined from the one or more images, and the result may be determined from the wavelength spectrum.

    Abstract: An Advanced Laser Fluorometer (ALF) can combine spectrally and temporally resolved measurements of laser-stimulated emission (LSE) for characterization of dissolved and particulate matter, including fluorescence constituents, in liquids. Spectral deconvolution (SDC) analysis of LSE spectral measurements can accurately retrieve information about individual fluorescent bands, such as can be attributed to chlorophyll-a (Chl-a), phycobiliprotein (PBP) pigments, or chromophoric dissolved organic matter (CDOM), among others. Improved physiological assessments of photosynthesizing organisms can use SDC analysis and temporal LSE measurements to assess variable fluorescence corrected for SDC-retrieved background fluorescence. Fluorescence assessments of Chl-a concentration based on LSE spectral measurements can be improved using photo-physiological information from temporal measurements. Quantitative assessments of PBP pigments, CDOM, and other fluorescent constituents, as well as basic structural characterizations of photosynthesizing populations, can be performed using SDC analysis of LSE spectral measurements.

    Abstract: A laser cavity two-photon spectroscopy includes a gain medium, a first reflector, a second reflector, an electrical pumping module, and a two-photon absorption cell. The first reflector is disposed at a side of the gain medium. The second reflector is movably disposed at a side of the gain medium relative to the first reflector. The electrical pumping module is electrically connected to the gain medium. Therefore, the gain medium is able to emit a light beam, which bounces back and forth between the first reflector and the second reflector and forms a laser beam through enhanced by the gain medium. The two-photon absorption cell disposed between the gain medium and the second reflector includes a plurality of two-photon absorption mediums. The two-photon absorption mediums absorb a portion of the laser beam reflected between the first reflector and the second reflector and then emit fluorescence.

    Abstract: A system and method for authentication of secure products is disclosed. The security feature contains a first component in the form of an emitter capable of emitting light in response to external pump light. The security feature also contains a second component in the form of a taggant that absorbs light in a spectrally narrow range compared to the broader excitation spectrum of the first material. In this manner the emitter and taggant work in combination with one another to create an emission response significantly dependent on the illumination wavelengths and unique to the specific combination of the components. The emitter and taggant can be in the form of a mixture. Further the emitter and taggant may be applied in close proximity to one another, such as within two separate coating layers on a suitable substrate.
