The idea of wavefront recording and reconstruction, known today as holography, was formulated by Gabor 1. His proof-of-principle experiment was done with the light of a high pressure mercury lamp; it ...

As one of the most widely adopted 3D sensing techniques, fringe projection profilometry (FPP) reconstructs the depth information of a scene from stereo images taken with sequential structured ...

Manufacturers are adopting automated optical inspection (AOI) systems based on phase shift profilometry (PSP) for applications in advanced packaging processes. Many of these processes use front ...
