This paper reviews recent developments of non-contact three-dimensional (3D) surface
metrology using an active structured optical probe. We focus primarily on those active non …

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

We present a 1 Mpixel single-photon avalanche diode camera featuring 3.8 ns time gating
and 24 kfps frame rate, fabricated in 180 nm CMOS image sensor technology. We designed …

Abstract Recently, the new Kinect One has been issued by Microsoft, providing the next
generation of real-time range sensing devices based on the Time-of-Flight (ToF) principle …

We survey the current state of millimeter-wave (mmWave) radar applications in robotics with
a focus on unique capabilities, and discuss future opportunities based on the state of the art …

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 …

Single-shot ultrafast optical imaging can capture two-dimensional transient scenes in the
optical spectral range at≥ 100 million frames per second. This rapidly evolving field …

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

Neural radiance fields (NeRFs) have become a ubiquitous tool for modeling scene
appearance and geometry from multiview imagery. Recent work has also begun to explore …
