    摘要: The inventors have discovered a method to improve image quality in holography and, for the first time, utilize lenses made from birefringent materials to advantageously split an incoming beam of either coherent or incoherent light into two coincident beams with different focal lengths that interfere with one another and thus create holograms free of electro-optical or pixelated devices. This discovery has many advantages over current methods to create holograms in which many components, including multiple lenses, other electro-optical devices, and/or beam paths are necessary to create holograms. The current invention provides a purely optical holographic process which has better performance and holographic simplicity, in addition to being able to miniaturize holographic processes more than is currently possible in state of the art holography systems.

    摘要: A method and device for measuring the mobility distribution of particulate elements using incoherent light holography, where the particulate elements are optically labeled. An elementary hologram is formed for each particulate element at a series of periodic moments representing the transfer function as a function of the instantaneous position of that element. The transfer function is modulated by a specified periodic transfer function for labeling each simple hologram and for generating conjugate elementary holograms integrated at each moment for forming a compound velocity hologram containing coded information for each particulate element. Each compound velocity hologram is decoded to obtain specified mobility information.

    摘要: A photorefractive device is provided for converting an image-bearing incoherent input beam to a high contrast coherent output beam the intensity of which varies as the square of the input intensity pattern. The device uses an incoherent image beam to write a holographic grating directly in a photorefractive medium. In one embodiment, a parallel, laterally displaced, telecentric system of lenses is used to split a quasi-monochromatic, incoherent image-bearing beam into two equal components. The two components are superimposed at the surface of the photorefractive medium to produce the hologram. In a second embodiment, the incoherent input beam is directed through a physically translating external grating to write the hologram in the photorefractive medium. The moving grating improves the diffraction efficiency of the hologram under the influence of an applied electric field and stabilizes the temporal response characteristics for signal processing. In both embodiments, the photorefractive medium is exposed to a coherent beam that picks up the image from the hologram and produces a coherent output beam having a high contrast replica of the input image.

    摘要: The invention relates to electro-optical media which make it possible to record holograms in real time. It consists in using a lamina of a selected material such as bismuth-silicon oxide, this lamina being subjected to a transverse electric field perpendicular to the fringes of the hologram to be inscribed, and in illuminating this lamina with a light beam which is not coherent with the two object and reference beams which interfere within this lamina.
