Paper Abstract

Liquid crystal panels, originally designed and fabricated for projection systems, are used as spatial light modulator in optical correlators or in fringe projection systems. An adapted driver electronics and measurements of the phase modulation behavior can lead to a dynamical phase modulating system with an almost linear modulation and a maximum phase shift of 2π. We built up a system with a LCD based spatial light modulator in order to realize the optical the reconstruction of digital holograms. Hologram reconstructions and the use of holographic interferograms for deformation detection are presented and future developments and applications are discussed.
