| 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. |
