Environmental effects on laser-induced fluorescence spectra of natural waters
Vodacek, Anthony; Philpot, William (Elsevier Science B.V., Amsterdam, 1987-02)Laser fluorosensing can be used to monitor dissolved organic carbon (DOC), but analysis of the data can be hindered by several environmental phenomena. These phenomena include attenuation of the laser beam and differential ... -
Excited state properties of Quinoxaline-substituted Platinum 1,2-Enedithiolates
Kaiwar, Sharada; Vodacek, Anthony; Blough, Neil; Pilato, Robert (American Chemical Society (ACS), 1997-04-09)The complexes (dppe)M{S2C2(2-quinoxaline)(R)}, where dppe = (diphenylphosphinoethane, M = Ni, Pd, and Pt, and R = H and Me, have as their lowest-energy band an intraligand charge transfer transition (ILCT). Excitation ... -
Fire temperature retrieval using constrained spectral unmixing and emissivity estimation
Ononye, Ambrose; Vodacek, Anthony; Kremens, Robert (The International Society for Optical Engineering (SPIE), 2005-06)Accurate retrieval of wildland fire temperature from remote imagery would be useful in improving prediction of fire propagation and estimates of fire effects such as burn severity and gas and particle production. The ... -
Inherent optical properties of the ocean: retrieval of the absorption coefficient of chromophoric dissolved organic matter from airborne laser spectral fluorescence measurements
Hoge, Frank; Vodacek, Anthony; Swift, Robert; Yungel, James; Blough, Neil (Optical Society of America, 1995-10)The absorption coefficient of chromophoric dissolved organic matter (CDOM) at 355 nm has been retrieved from airborne laser-induced and water Raman-normalized CDOM fluorescence. Four combined airborne and ship field ... -
Laser-induced fluorescence: Limits to the remote detection of hydrogen ion, aluminum, and dissolved organic matter
Philpot, William; Vodacek, Anthony (Elsevier Science B.V., Amsterdam, 1989-07)Laser-induced fluorescence (LIF) of dissolved organic matter (DOM) in lake water is, to a certain extent, indicative of water quality. DOM fluorescence intensity varies directly with connentration of the fluorescing organic ... -
Metallo 2,3-Disulfidothienoquinoxaline, 2,3-Disulfidothienopyridine, and 2-Sulfido-3-oxidothienoquinoxaline complexes: synthesis and characterization
Kaiwar, Sharada; Hsu, John; Vodacek, Anthony; Yap, Glenn; Liable-Sands, Louise; Rheingold, Arnold; Pilato, Robert (American Chemical Society (ACS), 1997-05-21)The 2,3-disulfidothienoquinoxaline complexes of Cp2Mo and dppePd and the 2,3-disulfidothienopyridine complexes of Cp2Mo were obtained as products from the S8 oxidation of the corresponding metallo-1,2-enedithiolate complexes. ... -
A new algorithm for global forest fire detection using multispectral images
Li, Ying; Vodacek, Anthony; Kremens, Robert; Ononye, Ambrose (The International Society for Optical Engineering (SPIE), 2003-09)Fire detection has been an active research field for many years and a number of algorithms have been proposed. These algorithms, however, are often inflexible in dealing with the spatial and temporal heterogeneity of ... -
Protonation-state-dependent luminescence and excited-state electron-transfer reactions of 2- and 4-Pyridine (-ium)-substituted metallo-1,2-enedithiolates
Kaiwar, Sharada; Vodacek, Anthony; Blough, Neil; Pilato, Robert (American Chemical Society (ACS), 1997-10-01)Luminescence and excited-state electron-transfer reactions of (dppe)Pt{S2C2(2-pyridine)(H)} and (dppe)Pt{S2C2(4-pyridine)(H)} (dppe = diphenyldiphosphinoethane) are enabled by protonation of the appended pyridine, thus ... -
Raman scattering by pure water and seawater
Bartlett, Jasmine; Voss, Kenneth; Sathyendranath, Shubha; Vodacek, Anthony (The Optical Society of America (OSA), 1998-05-20)Measurements of the magnitude and spectral distribution of the Raman-scattering coefficients of pure water ( b rw ) and seawater ( b rs ) are presented. Two independent measurements of the spectral distribution of the ... -
Remote optical detection of biomass burning using a potassium emission signature
Vodacek, Anthony; Kremens, Robert; Fordham, Andy; VanGorden, Stefanie; Luisi, Domenico; Schott, John; Latham, Don (Taylor and Francis Ltd, 2002-07)A remotely detectable signature for biomass burning that is specific to flaming combustion is found in the strong emission lines of potassium (K) at 766.5 nm and 769.9 nm. Ground level spectra of a test fire illustrate the ... -
Seasonal seawater optical properties of the U.S. Middle Atlantic Bight
DeGrandpre, Michael; Vodacek, Anthony; Nelson, Robert; Bruce, E.; Blough, Neil (American Geophysical Union, 1996)Optical properties of seawater on the U.S. Middle Atlantic Bight (MAB) were measured during four cruises spanning 1993-1994. Samples were collected in August and November 1993 and March and April 1994 along a cruise track ... -
Seasonal variation of CDOM in the Middle Atlantic Bight: terrestrial inputs and photooxidation
Vodacek, Anthony; Blough, Neil (The International Society for Optical Engineering (SPIE), 1997-02)Surveys of the fluorescence and absorption of chromophore-containing dissolved organic matter (CDOM) were made along a cruise line extending from the mouth of Delaware Bay southeast to the Sargasso Sea. With shallow ... -
A systematic approach to determining the limits of nanolithography at extreme NA
Bourov, Anatoly (2008-01)In optical imaging, separating the impact of the projection tool from the characteristics of the detector is key to understanding the limits of any exposure system. In semiconductor photolithography the detector is ...
