Guide to CCD-Based Imaging Colorimeters

Specially calibrated to replicate human spatial perception of brightness and color, imaging colorimeters and photometers are ideal in a broad range of measurement and inspection applications. With multiple options for CCDs, control electronics, filters, and lenses, these powerful tools can be tailored to...

Choosing a Measurement System for LED Sources, Luminaires and Displays

With the excitement surrounding the emergence of LED lighting and displays it is becoming increasingly important to be able to measure the performance of LEDs and LED-based systems in accurate and meaningful ways. This is even more important as LEDs are increasingly used as an alternative to more traditional...

Methods for Measuring Display Defects and Mura as Correlated to Human Visual Perception

Human vision and perception are the ultimate determinants of display quality, however human judgment is variable, making it difficult to define and apply quantitatively in research or production environments. Traditional methods for automated defect detection do not relate directly to human perception....

How to Use Imaging Colorimeters for Automated Visual Inspection of Displays

The use of imaging colorimeter systems and analytical software to assess display brightness and color uniformity, contrast, and to identify defects in displays is well established. A fundamental difference between imaging colorimetry and traditional machine vision is imaging colorimetry's accuracy in...
