Illumination is a critical component of any machine vision system and any undefined variations in illumination conditions can potentially affect the quality of the resulting image and in turn the accuracy and reproducibility of any measurements made from the image. In fact, the key parameter is actually the amount of light arriving at the image sensor.
The illumination source plays a critical role in this, but other components in the optical
system, and external factors can also have an influence on this. The new publication by Gardasoft discusses some of the causes of image brightness variation and possible solutions. Topics covered include: the need for constant image brightness; LED lighting control methods; factors affecting LED light intensity; other factors affecting image brightness; controlling light intensity and controlling image brightness using intelligent lighting.
