Frequency-domain Event-based Imaging for Selective Surveillance
Megan Birch, James Rick, Adrish Kar +2
Event-based cameras (EBCs) are an attractive sensing modality for surveillance due to their reporting of pixel-level radiance changes with microsecond resolution and high dynamic r…

Monocular passive event-based range-finding of airborne objects using the Scheimpflug principle
Nathan Meraz, Ronan Taneja, Rachel Chan +4
Passive 3D sensing is increasingly critical for early detection and tracking of small aerial vehicles (UAVs), where traditional active ranging can be tactically undesirable. We pre…

Scheimpflug cameras for range-resolved observations of the atmospheric effects on laser propagation
Nathan Meraz, Megan Birch, Ian Winski +4
This paper presents the development of Scheimpflug cameras for lidar and remote sensing with an emphasis on active and passive range-finding. Scheimpflug technology uses a tilted c…
