The process through which light rays falling on the surface on an object are sent back is called reflection of light. Thus, when light falls on the surface of an object it sends back the light. The ...

Diffuse reflectance spectroscopy is extremely useful for analyzing rough surfaced samples and powders. However, it is difficult to analyze most of the rough surfaced samples with in-compartment ...

Reflection from a smooth, flat surface is called specular reflection. This reflection obeys the law of reflection and is the type that happens with a flat mirror. A virtual image is an image from ...

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 ...
