Basics of Holography ( Cambridge University Press ) by P. Hariharan

By P. Hariharan

Fundamentals of Holography is a basic creation to the topic written via a number one employee within the box. It starts with the idea of holographic imaging, the features of the reconstructed photograph, and a few of the different types of holograms. useful points of holography are then defined, together with gentle resources, the features of recording media and recording fabrics, in addition to equipment for generating varieties of holograms and computer-generated holograms. ultimately, vital purposes of holography are mentioned, akin to high-resolution imaging, holographic optical components, info processing, and holographic interferometry.

3). 1. 1 Photographic materials Fig. 1. 51 Formation of a relief image by local tanning of the gelatin. spacing of the fringe planes is immediately apparent as a shift in the color of the image, which is reconstructed at a shorter wavelength than that used to record it. 1). This loss in diffraction efficiency can be minimized by having the object and reference beams incident at equal, but opposite, angles on the hologram, so that the fringe planes are normal to the surface of the photographic emulsion.

20 The reconstructed image actual reconstructed wavefronts. They can be evaluated if we retain the thirddegree terms in the expansion for the phase of a spherical wavefront [Meier, 1965]. 1 Classification of aberrations Hologram aberrations can be classified in the same manner as lens aberrations [Hopkins, 1950]. 11) where S is the coefficient of spherical aberration, Cx, Cy are the coefficients of coma, Ax, Ay are the coefficients of astigmatism, F is the coefficient of field curvature and Dx, Dy are the coefficients of distortion.
