    Abstract: Multiple energy sources, such as a laser and electrical field, are employed, in close coordination, spatially and temporally, to clean a sample, vaporize its material and excite vapor atoms for the purpose of atomic emission spectroscopy. These methods permit better monitoring and control of the individual processes in real time, lead to higher consistency and higher quality optical emission spectra, and enhance the measurements of non-conducting solids, liquids and gases. Additionally, a portable instrument is provided with both laser source and spectrometer optically coupled to a hand-holdable unit.

    Abstract: The invention provides a method for remote real-time detection and monitoring of polycyclic aromatic hydrocarbons (PAHs) and monoaromatics in a sample based on the use of laser-induced breakdown spectroscopy (LIBS). According to the method of the invention, detection and monitoring of PAHs and monoaromatics in a sample is carried out by the steps of using the energy from a pulsed laser to ablate a small quantity of a sample containing PAHs or monoaromatics, producing the emission spectrum of the resulting plasma plume by means of a spectrograph, detecting the intensities of the optical energy of specific features of the emission spectrum, measuring the intensities, and analyzing the measurements of the intensities. Analyzing the measurements of the intensities is done by comparing the measured maximum intensities with values in a previously acquired data base, calculating the ratio of the integrated intensity of specific features of the emission spectrum, and comparing the calculated ratios with values in a previously acquired data base.

    Abstract: A passive ranging system measured spectra of solar radiation off an adjacent spot (156) and a distal target (154). Reflected solar radiation and different attenuation are used to estimate target range. A comparison of absorption spectra from the solar illuminated distal target compared to the adjacent location is performed. Since the sun's position is always known, the increased absorption due to a distant target is derived from the differential between the adjacent spot and the distal target.
