System Construction for Recording Holographic Fringes

Abstract

In this thesis the holographic system was constructed by using He-Ne laser (power 1mW), optical system and holographic film plates. The system was designed in order to produce holographic interference fringes; this holographic fringe was captured by using a photographic camera. The Avometer and photocell detector was conducted in series and the maximum laser intensity (Imax) and the minimum laser intensity (Imin) intensity value were registered in the center of the interfere situations (zone plate), Then the MTF was calculated to illustrate the ability of this system to produce interference fringes (i.e. the visibility of fringes).
