White light reconstruction of image plane digital holograms

A real-time system is developed that employs a CCD sensor for recording and a reflective high-resolution liquid crystal display for reconstructing of image plane digital holograms. Two types of light sources, namely, the coherent (laser) and white light (LED) are used for optical reconstructions of static and dynamic object wave fronts. As expected, white light reconstructions exhibit improved properties compared to the corresponding monochrome reconstructions. However, these improvements become substantial in cases in which digital holograms are preprocessed by applying the common algebraic operations such as subtraction.
