Abstract

The paper analysis resolution of holographic reconstructive image of using the far field radiation emitted from incoherent multimode optical fiber bundle as the reference wave or illumination wave of object. It is demonstrated that if the coherence condition is satisfied, the point spread degree pr educed by mode dispersion is proportional to the distance, Zc, from reconstructive image to holofilm. Thus, when Z i.e. image-holograph, the resolution of re-image isn't nearly effected by the mode dispersion and the dimension of fiber cross-section, the experiment of deformation fringe with image-holograph is very well in accord with the theory expection.
