The techniques of small particle holography are extended in an elementary way to show that multiple exposure holography can be used to study the dynamic properties of particle fields. Experimental techniques for performing such a study are then described. Finally, as a typical example, a multiple exposure hologram of an aerosol is presented with a portion of the data extracted from it. The holo...

This paper presents a method for reducing noise in a digital hologram, which occurs during acquisition. The algorithm proposed initially transforms a digital hologram into frequency-domain data through a discrete cosine transform (DCT), and separates the object from the background in the transformed image. As a noise reduction method, a histogram modification method is applied to the object, wh...

In this paper we present an approach for the holographic imaging of objects composed of splines. It is based on an imaging method for lines and extended to fit the requirements for the visualization of 3D curves. The input object consisting of splines is decomposed into line segments. These segments are subsequently transferred into the holographic equivalent—a set of textured rectangles approp...

Techniques are presented which take advantage of the wavelength dependence of various phenomena in holographic interferometry. Image-plane interferograms illuminated with light containing multiple wavelengths exhibit color dispersion of the fringes. We extract from this dispersion, fullfield information concerning displacement components which are not disclosed by monochromatic illumination. Th...
