title: Holographic image reconstruction with an injection laser.
abstract: Injection lasers are promising as light sources for optical information processing devices. However, there remain many difficulties that must be overcome before they are put into practical use. Analysis is made of the effects of the insufficient spatial- and temporal-coherence on the reconstructed image of a hologram. The coherence property is represented by Deltalambda, the width of the spectrum, and by Deltad, the dimension of the light emitting region. The reconstructed image suffers lateral shift (Deltax, Deltay), as well as defocusing (Deltaz). Expressions for Deltax, Deltay, and Deltaz are given. Experimental results supporting the analysis are shown.
