Abstract

Laser radars are widely used for laser detection and ranging in a wide field of application scenarios. In the recent past, new sensing capabilities by transient light imaging have been demonstrated enabling imaging of light pulses during flight and the estimation of position and shape of targets outside the direct field of view. High sensitive imaging sensors are available give the chance to detect laser pulse in flight which are sparsely scattered in air. Theory and experimental investigation of arbitrary light propagation paths show the possibility to reconstruct the light path trajectory. This result could enable the remote localization of laser sources which will become an important reconnaissance task in future scenarios. Further, transient light imaging can reveal information about objects outside the direct field of view or hidden behind an obscuration by computational imaging. In this talk, we present different approaches to realize transient light imaging (e.g. time correlated single photon counting) and their application for relativistic imaging, real-time non-line of sight tracking and reconstruction of hidden scenes.
