Interferometric reconstruction of phase objects using diffuse `coding' and two holograms
(Elsevier, 1966-02-01)
In contrast with previously described multiply-exposed single holograms, used for interferometry according to a principle first described by Gabor, Stroke, Restrick, Funkhouser and Brumm, interferometric image `coding' and ...
White-light reconstruction of holographic images using transmission holograms recorded with conventionally-focused images and `in-line' background
(Elsevier, 1966-10-31)
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 ...
White-light reconstruction of holographic images using the Lippmann-Bragg diffraction effect
(Elsevier, 1966-03-01)
An extension of the 1962 Denisyuk method to record reflection holograms in Lippmann emulsions has permitted us to reconstruct monochromatic images with white light (e.g. sun) and demonstrate possibilities of simulating ...
Übererlaubter Positronenzerfall von K 38m , Sc 42 und Ti 43
(Springer-Verlag, 1961-02)
The maximum energies and the half-lives of three shortlived β + -activities near A =40 have been measured with a scintillation detector. The maximum β + -energies of 5.00±0.07 MeV (K 38m ), 5.32±0.10 MeV (Sc 42 ) and ...
Fuel cells--III. The propylene potential in low temperature cells
(Elsevier, 1964-12)
From the reproducible propylene potential observed at a platinum catalyst in 30% KOH solution, a potential of 0[middle dot]465 V (NHE) at 25[deg]C is calculated. The corresponding voltage for a propylene-oxygen cell is ...
Solution of the Non‐homogeneous Helmholtz Equation for Optical Gratings with Perfectly Conducting Boundaries
(W. H. Freeman and Co.Wiley Periodicals, Inc., 1966-04)
Voltammetry of tetra-alkyl ammonium salts at platinum in sulphur dioxide solution: Oxidation of the halides
(Elsevier, 1965-03)
The polarographic or voltammetric behaviour of a selected group of tetra-alkyl ammonium halides and related compounds in liquid sulphur dioxide was investigated, using a stationary disk platinum indicating micro-electrode ...
Polarographic reduction of maleic anhydride, maleate and fumerate in pyridine
(Elsevier, 1967-02)
Maleic and fumaric acids in pyridine show only the reduction behaviour of the pyridinium ion, which is produced when any Bronsted acid of aqueous pKa less than ca 9 is dissolved in pyridine. The diethyl esters each show ...
