Hologram interferometry of objects moving with constant acceleration has been investigated with special reference to the techniques of holographic addition and subtraction, which results in an extension of the range of measurement of conventional time average holography. Distribution of intensity in the fringes has been plotted for some typical cases.

The diffraction image of an incoherent bright annular test object is obtained by using Fourier transform method. The effect of transverse sinusoidal vibrations has been studied and results are given in graphical form for various sizes of the object. It is observed that in certain cases the presence of vibrations completely distorts the object. Hence a detailed analysis of image intensity distribution should prove useful in aerial reconnaissance work and performance evaluation tests.

The transmitted photon spectra of133Ba,22Na,137Cs,54Mn and60Co point sources are measured through different thicknesses of water, concrete and sand. The multiple-scatter peaks observed in these materials at 60, 90 and 100 keV energies respectively are found to be independent of incident photon energy and thickness of the medium.
