THE ASSESSMENT OF HIGH DYNAMIC RANGE LUMINANCE MEASUREMENTS WITH LED LIGHTING by Yulia I. Tyukhova A THESIS Presented to the Faculty of The Graduate College at the University of Nebraska In Partial Fulfillment of Requirements For the Degree of Master of Science Major: Architectural Engineering Under the Supervision of Professor Clarence Waters Lincoln, Nebraska April, 2012 THE ASSESSMENT OF HIGH DYNAMIC RANGE LUMINANCE MEASUREMENTS WITH LED LIGHTING Yulia I. Tyukhova, M.S. University of Nebraska, 2012 Adviser: Clarence Waters This research investigates whether a High Dynamic Range Imaging (HDRI) technique can accurately capture luminance values of a single LED chip. Previous studies show that a digital camera with exposure capability can be used as a luminance mapping tool in a wide range of luminance values with an accuracy of 10%. Previous work has also demonstrated the ability of HDRI to capture a rapidly- changing lighting environment with the sun.
