Abstract: A fundamental limitation of optical heterodyne interferometry is the narrow spectral band of the local oscillator. Studies are under way to overcome this issue, e.g., by using tunable setups. The present paper proposes to inspect the potential of a broadband local oscillator constituted by a supercontinuum source, i.e., a “white” laser. These non-linear optical devices have been commercially available in the last ten years, and their application in interferometry is yet to be explored.
