Overview of modulation techniques for spatially structured-light 3D imaging

Fiber-Based High-Speed Fringe Projection Profilometry

“…The use of 3D imaging to study the profile of objects has been used widely within engineering, medicine and art [1][2][3]. The ability to perform imaging through a narrow-gauge needle would enable surface imaging with minor impact on a patient; this would allow surgeons to make a better assessment of tissues before more traumatic surgical options are explored.…”
