Abstract

Light-measurement instrumentation based upon high-quality charge-coupled-devices (CCD) is currently in use for measuring the characteristics of electronic displays. When such array detectors are used to measure scenes or images having high contrasts or wide color variations, they can suffer from the effects of veiling glare or lens flare and thereby inaccurately measure the darker luminances because of a mixing of the scene luminances or colors. A liquid-filled simulated-eye design (SED) camera was constructed to improve the ability to measure such images by reducing the internal scattering that contributes to the veiling glare. This paper discusses the investigation of the use of various liquids, in particular the effects of scattering within the liquids.
