Learning to See Through Flare Open
Machine vision systems are susceptible to laser flare, where unwanted intense laser illumination blinds and distorts its perception of the environment through oversaturation or permanent damage to sensor pixels. We introduce NeuSee, the fi…

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…

Near-field coupling of absorbing material to subwavelength cavities Open
In conjunction with our previous work on spectral transmission dependence on geometric parameters for subwavelength slits, we have investigated the optical behavior with the inclusion of an absorber on the extraordinary optical transmissio…

Validation of infrared sensor model with field-collected imagery of unresolved unmanned aerial vehicle targets Open
An infrared (IR) sensor model is validated using experimentally derived peak pixel signal-to-noise ratio (SNR) versus range for detection of either an unresolved or a resolved unmanned aerial vehicle (UAV) target. The model provided estima…
