ABSTRACT:
Disclosed herein are systems and methods for measuring color and contrast in specular reflective devices such as interferometric modulators. To make color and contrast determinations, light reflected from a specular reflective device may be measured in-line with illumination of the device. The measurements may include measuring the spectra of light reflected from the device being tested as well as from specular bright and dark standards. The spectra may be used to determine a reflectance spectrum and color parameters for the specular reflective device.
