Machine vision is a key control element for countless robotics and automated systems, as well as the basis for a wide variety of systems that measure and extract information from objects. But without proper illumination, vision systems are essentially blind.

Lighting requirements for machine vision are relatively straightforward. Whatever's used to illuminate the objects in the field of view must provide adequate contrast for features of interest. It must also be:

Reintroducing machine vision: take another look at an important quality analysis tool.(REINTRODUCING MACHINE VISION)
Quality ; Over the years, machine vision has become an important tool for quality analysis. As a technology, it is well-suited for on-line improvement of the manufacturing process. Yet machine vision is not as ubiquitous on the plant floor as might be imagined. According to some market experts, operators
Machine vision sensors, systems penetrate new realms. (Product Focus: Machine Vision).
Control Engineering ; Seeing usually means believing, but it less often means perceiving. Though this remains all too true for human eyes, their mechanical counterparts are becoming increasingly sophisticated, efficient, intelligent, network enabled and, yes, affordable. These and other improvements are fueling the
Machine Vision Solves Test Challenges.
Fiberoptic Product News ; For integrated circuit (IC) manufacturers, machine vision is an essential component in the quest to achieve competitive economies of scale. Machine vision uses video cameras, frame grabbers, and computers to replace human vision in evaluation and test tasks -- tasks that are extremely precise,
Machine vision aids quality inspection: machine vision has evolved to become a fast and reliable tool for quality control inspection.(QUALITY 101)
Quality ; Machine vision is the application of computer vision to industry and manufacturing. More specifically, it is the automatic acquisition and analysis of images to obtain desired data for controlling a specific activity. It has evolved to become a fast and reliable tool for quality control inspection.
Machine vision applications in discrete-parts manufacturing
Manufacturing Engineering ; Machine Vision Association First of all, it may be useful to define what does not constitute machine vision. Machine vision is not human vision, rather machine vision is competing directly with human vision as an inspection facility. Machine vision is not science, rather it is systems engineering.
Seeing machine vision in a different light: as machine vision comes of age, get to know this yield enhancement tool and its capabilities. (Management).
Quality ; In case you haven't looked lately, machine vision technology has done a lot of growing up since the first systems arrived on the scene some 30 years ago. Once thought of primarily as inspection tools useful for separating good parts from bad, machine vision systems these days are increasingly being
Machine Vision Course for Manufacturing Engineering Undergraduate Students
Journal of Manufacturing Systems ; Abstract A 10-week course was designed with funding from the Society of Manufacturing Engineers (SME) and input from industry representatives, to offer upper division engineering students a course on advanced automation. The objective was to provide engineering students theoretical and hands-on
