Abstract

Experimental results from a fine-resolution three-dimensional (3-D) imaging method are presented. An object is flood illuminated with coherent light from a frequency-tunable laser. Electronic holograms are then recorded for a series of laser frequencies. These recordings are digitally assembled into a 3-D data array that is Fourier transformed to yield a 3-D image. 3-D imaging with 4.2-μm range resolution using a broadly tunable dye laser is demonstrated.
