Full web measurements In electronics, extremely fast technical development during the past decade has been seen in digital imaging elements. Although the driver has been consumer applications, the advances in digital imaging have opened new industrial measurement opportunities and tremendously improved the performance of earlier measurement systems. This development has also had important implications for
