We present a new approach for single shot multi wavelengths contouring using the broad spectrum of a fs-laser. The spectral distribution of a fs-laser contains a multitude of discrete frequencies which principally can be separated and simultaneously used for gathering holograms with different wavelengths. In order to investigate the characteristics of this approach, we have built up a setup using a tuneable dye-laser. Several wavelengths of the dye laser have been spatially distributed for the reference wave on the hologram target. Holograms at different wavelengths are recorded and superimposed numerically afterwards to guarantee resemblance to the fs-laser setup. In this paper we describe the theoretical background, derive an algorithm for noise-reduced reconstruction and show corresponding experimental results.
