This section explains the physical and geometric principles behind the LumiScan X. It is written for engineers who are new to light field imaging, and it gives readers who know computer vision and optical measurement enough detail to judge what the LumiScan X measures and what limits its results. You do not need it to install or operate the camera; for that, see Installation and LumiScan Software.

  • Light Field Imaging: the plenoptic function, the four-dimensional light field, and how parallax between viewpoints yields depth.

  • Light Field Acquisition Architectures: microlens-based plenoptic cameras and camera arrays compared, with their trade-offs.

  • How LumiScan X Works: camera arrangement, calibration and depth reconstruction of the LumiScan X, the factors that determine measurement quality, a summary and the references.
