Imaging Colorimetry: Accuracy in Display and Light Source Metrology


CCD-based instruments provide accurate photometric and colorimetric data for each image pixel, which enables precise characterization of displays, instrument panels, light sources and luminaires for parameters including color, luminance, uniformity, contrast, mura and defects, and view angle performance. In this article we look at the basic operating principles and performance tradeoffs of imaging colorimeters, a class of instruments that enable spatially resolved measurements of color and luminance that are directly applicable to displays and solid-state sources.
