Reconstruction of a Fraunhofer hologram recorded near the focal plane of a transforming lens
Abstract
A Fraunhofer hologram of M x N array of binary coded data is recorded in a plane located near the focal plane of a transforming lens, and the amplitude transmittance of that hologram is calculated. In the reconstruction process a plane wave as well as a spherical wave with a Gaussian amplitude distribution is applied, and the field distribution in the image plane is theoretically found. All calculations are performed for a linearly recorded hologram of a finite aperture. Intermodulation noise is neglected.
