EVT

Enhanced Visual Testing 

EVTEnhanced Visual Testing is the application of visual testing using high-resolution camera systems. EVT was established in response to concerns raised on the reliability of visual testing (VT) at the end of the 1990s. The essential parameters for EVT are illumination, examination distance, viewing angle, scanning speed, positioning accuracy and sizing of indications. Since its introduction, EVT has adopted further image enhancements and analysis capabilities to provide increased reliability.
