Multiple-Sine-Slit Microdensitometer and MTF Evaluation for High Resolution Emulsions 2: MTF Data and Other Recording Parameters of High Resolution Emulsions for Holography

By means of the Multiple-Sine-Slit Microdensitometer (MSSM), MTF's up to 1500 c/mm have been evaluated for five photographic plates for holography, Agfa-Gevaert Scientia 10E75, 8E75, 8E75B, and Kodak 649-F and Type 120-02. For comparison, an as-if-MTF has also been derived from diffraction efficiency measurements. In addition sensitivity at lambda = 633 nm, the macroscopic characteristic tau(A) vs logE and alpha(2)(E), and scattered-flux data are reported for these five plates.

Writing Characteristics of MnBi Films for Holographic Recording

In writing holograms on MnBi films, the two important parameters are the total beam energy and the thermal modulation depth, both imposed by the physical properties of the film. Different combinations of the two parameters lead to different types of holograms. Experimental results will be given to demonstrate the predicted varieties of recordings. Accurate measurements of diffraction efficiencies and interpretations of the result will be given.

The Diffraction of X-Rays by Multilayer Stearate Soap Films

AbstractThe diffraction of X-rays by multilayer stearate soap films has been studied as a function of (a) the number of diffracting layers and (b) the bivalent metal present. Both “Y” and “X” type structures have been built and analyzed with Al and C Kα radiation. The measured diffraction efficiency is compared with that predicted theoretically and with that obtained from a single crystal such as potassium acid phthalate.
