WHITE‐LIGHT RECONSTRUCTION OF COLOR IMAGES FROM BLACK‐AND‐WHITE VOLUME HOLOGRAMS RECORDED ON SHEET FILM

The method of ``white‐light reflection holography'' first described by Stroke and Labeyrie (Physics Letters 20, 368, March 1, 1966) and subsequently verified by a number of authors, has now been extended to the recording of volume holograms in 6–7‐μ‐thick Kodak 649F emulsions on sheet film, with a quality in the reconstructed images comparing favorably with the images reconstructed from the 17‐μ‐thick emulsions on glass plates used heretofore. The results presented have also permitted us to further verify a simple ``crystallographic'' theory of the method, first used by Stroke and Labeyrie (ibid.) and further described by G. W. Stroke in a subsequent paper.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/70381/2/APPLAB-9-5-215-1.pd

A posteriori image-correcting "deconvolution" by holographic fourier-transform division

Division of spatial field distributions in the Fourier-transform domain for "resolution-retrieving", "corrective" image deconvolution of the "smearing" resulting from extended "instrument functions" in optical imaging, spectroscopy and radio-astronomy may be accomplished by a "two-filter" holographic scheme.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/33306/1/0000700.pd

Use of extended and prepared reference objects in experimental Fourier transform X-ray holography

The use of one or more gold nanoballs as reference objects for Fourier Transform holography (FTH) is analysed using experimental soft X-ray diffraction from objects consisting of separated clusters of these balls. The holograms are deconvoluted against ball reference objects to invert to images, in combination with a Wiener filter to control noise. A resolution of ~30nm, smaller than one ball, is obtained even if a large cluster of balls is used as the reference, giving the best resolution yet obtained by X-ray FTH. Methods of dealing with missing data due to a beamstop are discussed. Practical prepared objects which satisfy the FTH condition are suggested, and methods of forming them described.Comment: 7 pages, 2 figures, submitted to Applied Physics Letter
