Abstract :
Wavelength scanning digital holography using laser diode current modulation is presented. A series of holograms are recorded while the phase of hologram is swept through wavelength scanning. The object wave component is extracted from recorded holograms by applying temporal frequency analysis to each pixel of the holograms. The proposed technique allows us to record a large object as digital hologram using simple and cost effective optical setup.
