Phase Tandem Low-Coherence Interferometry for Surface Vibration Measurements

Phase Tandem Low-Coherence Interferometry for Surface Vibration Measurements

The development of optical methods for surface vibration measurements is currently of great interest. We propose a modified tandem low-coherence technique that utilizes the phase information of the low-coherence signal to detect surface vibrations. The resolution of this scheme is less than 1 nm for...
