Knowledge base
Learn more about machine vision! In our knowledge base we are explaining key technical terms about image processing. We give you an overview to topics like 3D machine vision or the established standards like CameraLink, GigE Vision or GenICam.
Illumination
Selecting and correctly configuring the optimal illumination setup is one of the key factors when designing a vision system. Missing image information caused by incorrect illumination makes subsequent analysis much more difficult or even impossible, as no analysis algorithm can recover information that has never been captured.
Advanced coaxial illumination
Illumination for homogeneous illumination of uneven surfaces.
Angle of illumination
Probably the most important factor that governs how the captured image appears is the angle at which the light falls on the target.
Backlight illumination - diffuse
Technique positioning a diffuse illuminator behind the object to produce a silhouette.
Bright field illumination
Most common technique for illuminating diffuse, non-refelctive objects.
Collimated backlight illumination
This form of backlighting is useful for measurement tasks that require a homogeneous illumination with no scattered ligth.
Collimated coaxial illumination
Collimated light source especially useful for detection of shallow flaws on on flat, reflective objects.
Collimated light
Collimation is a method of controlling illumination so that the light rays are parallel.
