  3. The Race To The Starting Line: Edge-Emitting Diode Lasers vs. VCSELs For The Automotive Lidar Market 3/13/2018

    The competition to be the leading diode laser source for automotive lidar is not a race to the top, but rather a race to the starting line. Before reaching the goal to implement lidar ADAS in consumer vehicles by 2020, there must be at least one year of certification and testing before going to market.

  8. Frequency Comb Research Advances Using Tunable Diode Lasers 8/12/2015

    The discovery of the optical frequency comb and the breakthrough work of Hänsch and Hall in refining the frequency comb technique have revolutionized the field of scientific metrology. In this application note, we will look more closely at how the so-called “microcombs” are generated and what the role of external cavity diode lasers (ECDLs) is in the microcomb generation process. We will briefly discuss how the microcomb is evolving into a compact, versatile tool with increasing application, for example, in the field of molecular spectroscopy. Although still maturing, the field of microcombs has the potential to transform various other disciplines, leading to compact comb generation platforms with numerous applications.

  9. Standoff Midwave Infrared Hyperspectral Imaging Of Ship Plumes 8/5/2015

    Characterization of ship plumes is very challenging due to the great variety of ships, fuel, and fuel grades, as well as the extent of a gas plume. In this work, imaging of ship plumes from an operating ferry boat was carried out using standoff midwave (3-5 m) infrared hyperspectral imaging. Quantitative chemical imaging of combustion gases was achieved by fitting a radiative transfer model. Combustion efficiency maps and mass flow rates are presented for carbon monoxide (CO) and carbon dioxide (CO2). The results illustrate how valuable information about the combustion process of a ship engine can be successfully obtained using passive hyperspectral remote sensing imaging.

  10. Airborne Thermal Infrared Hyperspectral Imaging For Mineral Mapping 8/5/2015

    In order to illustrate the benefits of thermal infrared hyperspectral imaging (HSI) for mineral mapping, an airborne survey was carried out over an open-pit mine in the Thetford Mines (Qc, Canada) area. The results show how high spectral resolution data facilitates temperature emissivity separation (TES) and atmospheric correction in order to retrieve a thermodynamic temperature map of the area and its associated spectral emissivity datacube. Mineral mapping of various minerals such as lizardite, serpentinite, and quartz was achieved through linear unmixing of the emissivity data using reference emissivity curves found in spectral libraries. The results illustrate the potential of TIR HSI for airborne mapping of silicate minerals.
