Lecture 7 Information capacity of volume holograms David J Brady Duke University Lecture 7 Information capacity of volume holograms wwwdispdukeedudbradycoursesholography Lecture 5 Display Holography. When the object is a grating with a single frequency at the coherent cutoff the 1and 1 orders are just barely accepted by the aperture of the imaging system These three beams then produce a fringe pattern at the cutofffrequency Ifthe grating frequen A more detailed explanation of holography can be found in the PhD theses of Dr R Barth and Dr M Sch57535rmann and in the Diploma thesis of T Gorniak all carried out in our group Furthermore this introduction is based on the corresponding chapt Muhammad Hasan Danish Khan. University of . Vaasa, Finland. Outline. Introduction. Principles. Optical holograms. Applications. References. Holography. Is a technique that allows the light scattered from an object to be recorded and later reconstructed so that when an imaging system (a camera or an eye) is placed in the reconstructed beam, an image of the object will be seen even when the object is no longer present. .
