    Elimination of the Unwanted Image in Diffraction Microscopy (1951)
    [s.l.] : Nature Publishing Group
    Nature 167 (1951), S. 190-191 
    Details
    ISSN: 1476-4687
    Source: Nature Archives 1869 - 2009
    Topics: Biology , Chemistry and Pharmacology , Medicine , Natural Sciences in General , Physics
    Notes: [Auszug] The position is made clearer by taking a simple case. We consider the system in which both the production and reconstruction of the hologram occurs in a parallel beam of coherent light (or electrons). This corresponds to the important practical case of the 'transmission microscope' of Haine and ...

    Notes: [Auszug] The (development of various two-stage processes of image formation1, in which the wave-length may be altered between object and image, makes it profitable to consider whether the wave-length can be introduced. Since wave-length is inversely proportional to refractive index, the form: \Lrhr sin a ...

    Notes: [Auszug] Longitudinal section of duodenum (4.). x 40 We have obtained satisfactory results with a considerably modified method which is less time-consuming, more economical and essentially simple. It is based on the conversion of the radio-opaque silver iodide to metallic silver by a photographic ...

    Gabor Diffraction Microscopy: the Hologram as a Generalized Zone-Plate (1950)

    Topics: Biology , Chemistry and Pharmacology , Medicine , Natural Sciences in General , Physics
    Notes: [Auszug] It should be noted that a zone plate is a particular case of an artificially constructed hologram, corresponding to the introduction of a second coherent point source into the diverging beam from the first point source. A zone plate, moreover, when suitably arranged in front of a point source, duly ...

    Notes: [Auszug] A bromide enlargement from a hologram (A) (part only is reproduced) was taken and all the important lines (as judged by the operator) were inked in with indian ink using a mapping pen. Attention was confined, so far as possible, to the fringes produced by the object (a micrometer eyepiece scale), ...
