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 ...

Accurate and robust 3D imaging of specular, or mirror-like, surfaces is crucial in fields such as industrial inspection, medical imaging, virtual reality, and cultural heritage preservation. Yet ...

Retinal image structure contains an entangled mixture of information about three-dimensional (3D) shape, surface reflectance and the illumination field. Although the veridical separation of these ...

Laboratory experiment demonstrating the proof of principle of the new technology. A mixed reflectance scene is scanned with a laser scanner (left). After computational separation of matte and specular ...

Traditionally, the form of highly sloped surfaces has been challenging application for optical profilers using coherence scanning interferometry (CSI). Highly sloped surfaces exist in virtually all ...

Eerie, oversized eyes and artificially gleaming pupils. Though human in form, the somewhat awkward face is reflected on the ...

Left: Schematic of the introduced prototype device for the measurement of specular surfaces, comprised of an unpolarized display and a polarization camera. Right: Measurement example: Object, camera ...

A new method significantly advances 3D imaging of reflective surfaces. The approach integrates techniques known from high-precision optical 3D metrology and computer vision, and could benefit ...
