Abstract

We present a novel device for fast, reproducible and low contrast minimum resolvable contrast (MRC) measurements based on an OLED microdisplay. The high intensity resolution and luminosity of the employed display allows the generation of target contrasts well below 0.5 % at brightness levels of more than 500 nits. Using a 4 m collimator we were able to perform an MRC measurement over the full relevant spatial frequency range of a recently developed terrestrial TV camera system. The small pixel pitch of the display allowed us to use a short collimator length and to perform MRC measurements with high frequency resolution.
