In high-performance display measurement solutions (such as Radiant’s scientific-grade ProMetric® Imaging Photometers and Colorimeters), images are captured by a high-resolution digital camera that receives electromagnetic radiation (light) from the DUT in the form of photons. Fine-grain defects such as lines and spots can be obscured by the moiré pattern in a test image, but will be visible to end consumers using the device.ĭisplay test and measurement systems typically work by capturing an image of a DUT (device under test) and then analyzing that image to find any defects or quality issues. To test display devices for quality in the production process, we need to eliminate the moiré effect to obtain precise measurements and detect defects on the screen.
