A method of distributed coding of digital images was proposed in imitation of the holographic principle of image recording.
In this article, a hew method of color holography is suggested. Only a single wavelength laser is needed as light source, and any monochromatic holographic plate for photographic recording. The hologram obtained is then reconstructed by means of white light transmission. Experiments have been carried out using flower and three color circles as objects, the reconstructed pictures are presented here.
The multiple-images produced by Fresnel hologram and lensless Fouriertransform hologram of an array of lenslets and their aberrations have been investigeted. The Characteristic features of these two optical systems are compared; the cause of the appeared aberrations, the various factors that trove influence upon the resolution and aberrations and the methods of increasing the resolution and decreasing the aberrations are discussed. The experiment and its analysis show that such aberrations are due to the ce...
In order to clarify the principle of real-time acoustical holography employing a liquid surface, it is necessary to analyse the transformation from sound signal to rippled liquid-surface (i.e. hologram) and that from hologram to optical image. In this paper, a more thorough theoretical analysis of the two transformations is made by means of Fourier analysis technique. The formulas calculating the deformation caused by the "reference" sound beam and the "object" sound beam, which has arbitrary spatial distri...
