Non-line-of-sight imaging using phasor-field virtual wave optics

Algorithms based on diffractive wave propagation of light offer effective imaging of complex scenes hidden from direct view.

Subjects Computer science Imaging and sensing Abstract 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 many potential applications 1 , 2 , 3 , 4 , 5 , 6 , 7 , 8 , 9 , existing methods lack practical usability because of limitations including the assumption of single scattering only, ideal diffuse reflectance and lack of occlusions within the hidden scene. By contrast, line-of-sight imaging systems do not impose any assumptions about the imaged scene, despi
