Glossaire technique
Advanced illumination solutions
Getting the best image is a combination of the right illumination, the right lensing and filters to complement and enhance the features in the image with a camera that is set up correctly.
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.
Cable testing and validation
As vision systems evolve, we tend to see more cameras per system, faster data rates and the use of network technology between the camera and PC. All these factors increase demands on the cabling and poor cabling or incorrect network switches can have serious effects.
Cable: Definition of cable types
In imaging and machine vision selecting the right cable can be an important consideration. A wide range of technical requirements, including mechanical, thermal or chemical impacts, have to be considered. The following table gives a short overview of the most common cabling specifications used for imaging and available from STEMMER IMAGING.
Câbles : Cat6 / Cat 5 / Paire torsadée
Paire torsadée avec une fréquence de fonctionnement jusqu’à 250 MHz pour la transmission de langue, de données, multimedia et les réseaux ATM.
Câble Cat6 | Câble Cat 5/5e | Paire torsadée
Câbles pour applications robotiques
Câble avec haute résistance à la torsion et bonne propriété de flexion et qui est apte à l’usage dans les applications robotiques.
Câbles pour chaînes porte-câbles
Câble adapté aux flexions fréquentes dans les systèmes des chaînes porte-câble et qui a ainsi une plus longue durée de vie qu’un câble standard.
