Abstract
A technique is presented by which holograms can be recorded by scanning an object or scene with an optically heterodyned Fresnel zone pattern. The experimental setup, based on optical scanning holography, is described and experimental results are presented. We apply the scanning holography technique to three-dimensional (3-D) reflective objects for the first time and address the unique requirements for such a system. Holographic recording and numerical image reconstruction are discussed using a system point spread function (PSF) approach. We demonstrate numerical image reconstruction of experimentally recorded holograms by two techniques: deconvolution with a simulated PSF and an experimentally acquired PSF.
