Abstract
We present a technique for programming the source of the spherical reference illumination in digital in-line holography using digital micromirror devices. The programmable point source is achieved by individually addressing the elements of a digital micromirror device to spatially control the illumination of the object located at some distance from the source of the spherical reference field. By moving the location of the “ON” element on the digital micromirror device, translation of both the source of the spherical reference beam and the captured holograms is achieved. Results obtained through numerical recon struction of these translated holograms shows the possibility of expanding the field of view by about 263%.
