Emerging single-photon-sensitive sensors produce picosecond-accurate time-stamped
photon counts. Applying advanced inverse methods to process these data has resulted in …

BACKGROUND Imaging technologies, which extend human vision capabilities, are such a
natural part of our current everyday experience that we often take them for granted …

How to image objects that are hidden from a camera's view is a problem of fundamental
importance to many fields of research 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18 …

Imaging objects outside a camera's direct line of sight has important applications in robotic
vision, remote sensing, and many other domains. Time-of-flight-based non-line-of-sight …

Non-line-of-sight imaging allows objects to be observed when partially or fully occluded from
direct view, by analysing indirect diffuse reflections off a secondary relay surface. Despite …

We present a novel theory of Fermat paths of light between a known visible scene and an
unknown object not in the line of sight of a transient camera. These light paths either obey …

Time-of-flight (ToF) imaging has become a widespread technique for depth estimation,
allowing affordable off-the-shelf cameras to provide depth maps in real time. However …

By using time-of-flight information encoded in multiply scattered light, it is possible to
reconstruct images of objects hidden from the camera's direct line of sight. Here, we present …

The ability to record images with extreme temporal resolution enables a diverse range of
applications, such as fluorescence lifetime imaging, time-of-flight depth imaging and …

Conventional sensor systems record information about directly visible objects, whereas
occluded scene components are considered lost in the measurement process. Non-line-of …
