Non-line-of-sight imaging using phasor-field virtual wave optics
Xiaochun Liu,Ibón Guillén,Marco La Manna,Ji Hyun Nam,Syed Azer Reza,Toan Huu Le,Adrian Jarabo,Diego Gutierrez,Andreas Velten +8 more
TL;DR: This work shows that the problem of non-line-of-sight imaging can be formulated as one of diffractive wave propagation, by introducing a virtual wave field that is term the phasor field, and yields a new class of imaging algorithms that mimic the capabilities of line- of-sight cameras.
Journal ArticleDOI
Wave-based non-line-of-sight imaging using fast f-k migration
TL;DR: This work introduces a wave-based image formation model, f-k migration, that is both fast and memory efficient, robust to specular and other complex reflectance properties, and shows how it can be used with non-confocally scanned measurements as well as for non-planar sampling surfaces.
Journal ArticleDOI
State-of-the-art active optical techniques for three-dimensional surface metrology: a review [Invited].
TL;DR: This paper reviews recent developments of non-contact three-dimensional (3D) surface metrology using an active structured optical probe and discusses principles of each technology, and its advantageous characteristics as well as limitations.

A Theory of Fermat Paths for Non-Line-Of-Sight Shape Reconstruction
Shumian Xin,Sotiris Nousias,Kiriakos N. Kutulakos,Aswin C. Sankaranarayanan,Srinivasa G. Narasimhan,Ioannis Gkioulekas +5 more
TL;DR: This work presents 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, and presents an algorithm, called Fermat Flow, to estimate the shape of the non-line-of-sight object.
Proceedings ArticleDOI
Reconstructing Transient Images from Single-Photon Sensors
TL;DR: In this work, an imaging system that builds on single photon avalanche diode (SPAD) sensors to capture multi-path responses with picosecond-scale active illumination is designed and evaluated and inverse methods that use modern approaches to deconvolve and denoise measurements in the presence of Poisson noise are developed.

Optical coherence tomography

TL;DR: OCT as discussed by the authors uses low-coherence interferometry to produce a two-dimensional image of optical scattering from internal tissue microstructures in a way analogous to ultrasonic pulse-echo imaging.
Journal ArticleDOI
The rendering equation
TL;DR: An integral equation is presented which generalizes a variety of known rendering algorithms and a new form of variance reduction, called Hierarchical sampling, which may be an efficient new technique for a wide variety of monte carlo procedures.

Modeling the interaction of light between diffuse surfaces
TL;DR: In this paper, a method is described which models the interaction of light between diffusely reflecting surfaces, and the resultant surface intensities are independent of observer position, and thus environments can be preprocessed for dynamic sequences.

Solid-state time-of-flight range camera
Robert Lange,Peter Seitz +1 more
TL;DR: In this paper, the concept of a real-time range camera without moving parts is described, based on the time-of-flight (TOF) principle, which operates with modulated visible and near-infrared radiation, which is detected and demodulated simultaneously by a 2D array of lock-in pixels employing the charge-coupled device principle.

Andreas Velten,Thomas Willwacher,Otkrist Gupta,Ashok Veeraraghavan,Moungi G. Bawendi,Ramesh Raskar +5 more
TL;DR: A three-dimensional range camera able to look around a corner using diffusely reflected light that achieves sub-millimetre depth precision and centimetre lateral precision over 40 cm×40cm×40 cm of hidden space is demonstrated.
