We report a multi-wavelength digital holographic tomography system based on a fiber-based spectral interferometer. Instead of using tunable lasers, a relatively inexpensive broadband source was used as the light source. Hundreds of 2-D "synthesized holograms" (or object wavefields) were obtained by transversal scanning of a probe beam within a few seconds. Holographic images of an object volume were numerically reconstructed from each synthesized hologram and tomographic images were obtained by superposition of all the image volumes.
