Multi-spectral SWIR lidar for imaging and spectral discrimination through partial obscurations Open
We have developed a multi-spectral SWIR lidar system capable of measuring simultaneous spatial-spectral information for imaging and spectral discrimination through partial obscurations. We employ objects in the presence and absence of a se…

Surface-Enhanced Raman Spectroscopy for Environmental Monitoring of Aerosols Open
Surface-enhanced Raman spectroscopy (SERS) is conducted from single aerosol particles held in a linear electrodynamic quadrupole trap. SERS measurements from two representative types of ambient aerosol particles, semi-liquid and solid aero…

Real-time sensing of bioaerosols: Review and current perspectives Open
Detection of bioaerosols, or primary biological aerosol particles (PBAPs), has become increasingly important for a wide variety of research communities and scientific questions. In particular, real-time (RT) techniques for autonomous, onli…
