Liquid crystal displays are gaining market share. As prices fall, users want brightness and viewing angles comparable to that of conventional displays. A display's visual performance usually is measured with goniometric methods based on mechanical angular scanning of emission and/or reflectivity. The technique is sensitive, has high resolution, but is slow. Autronic-Melchers GmbH has developed ConoScope, an all-optical system that quickly measures viewing performance. The key component of the system is a high-performance Fourier transform lens. It covers an aperture angle of up to...Read full article
