Range-resolved vibrometry using a frequency comb in the OSCAT configuration.
Two methods for performing range-resolved vibrometry measurements using frequency combs are presented. A modified correction algorithm taking into account the differences from the typical dual comb spectroscopic technique is developed. Results are presented showing the recovery of a human voice sample and other sounds from different vibrating surfaces, including a diffuse wall and a glass slab. When multiple surfaces are present, range selection makes it possible to select the surface from which the vibration is demodulated.
