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

White-light reconstruction of holographic images using transmission holograms recorded with conventionally-focused images and `in-line' background

A new extension of Gabor's wavefront-reconstruction principle permits to reconstruct three-dimensional images by transmission of white light through a hologram recorded in a new arrangement using an `in-line' coherent background superposed onto a conventionally focused.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/33413/1/0000814.pd

Spectroscopic implications of new holographic imaging methods

Significant increases in luminosity, detection and resolution capabilities may result from extending to spectroscopic and astronomical instruments some of the new advances, recently made in the field of wavefront-reconstruction imaging (holography), first described by D. Gabor in 19481) 2) 3) 4).The recent advances 4-11) of which we have briefly described some early aspects elsewhere have already permitted us to obtain spectra in a holographic Fourier- transforming 7) 8) arrangement, using no scanning in the interferometer, and displaying the spectra by optical Fourier-transform reconstruction from the interferometric hologram 9), rather than by digital computation. In another work, we have now been able to holographically compensate a posteriori for the "slit spreading-effect", in a coherent-light imaging system, and to retrieve the resolution by a corrtion-reconstruction method 10) 11). "Erasing" of selected image portions, by actually adding the complex amplitudes in two images, 180[deg] out of phase, in a holographic arrangement has also been achieved 12) and may be used for increasing detection of selected image portions in astronomical and spectroscopic plates. Previously unpublished advances and some details of the new holographic imaging methods are given.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/33391/1/0000790.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
