    Quadrant Fourier Transforms and their Use in Wave Decoding (PM4D.4)
    Presenter: Chensheng Wu, University of Maryland College Park

    A new optical structure with two identical micro-lens arrays (MLAs) has been found useful in simplifying the gradient field extraction of an arbitrary wave. In particular, it speeds up the efficiency of decoding and localizing intended optical signals embedded in an arbitrary optical wave.

    Visualizing and Quantifying Methane and Natural Gas Emissions Using Lasers and Small Semi-autonomous Drones (AM4F.1)
    Presenter: Michael Frish, Physical Sciences Inc.

    We describe man-portable and aerial near-IR laser sensor platforms which spatially scan a laser beam to create quantitative plume images. These tools locate, visualize, and deduce natural gas (methane) emission rates at small infrastructure sources.

    Combined MIR Quantum Cascade Laser Reflectance Spectroscopy and Laser-Induced Breakdown Spectroscopy for Mineral Quantification (AM4F.2)
    Presenter: Francis Vanier, National Research Council Canada

    Mid-infrared reflectance spectroscopy and laser-induced breakdown spectroscopy are combined to provide the quantitative mineral composition of rocks. Measurement results for kaolinite are presented and a relative error of kaolinite abundance of 0.8 % is obtained.

    Measurement of Trace Gases from a Fracking Site Using Mid-Infrared Dual Comb Spectroscopy (AM4F.3)
    Presenter: Eleanor Waxman, NIST

    We used a MIR dual frequency comb spectroscopy system to measure emissions at a fracking site. We present preliminary measurements of methane, ethane, and higher hydrocarbons. The methane shows good agreement with a co-located point sensor.
