Abstract in another language
We present an optical detection system based on a modified Michelson interferometer which is capable of measuring the absolute amplitudes and phases of microacoustic vibrations at frequencies up to several gigahertz. The setup involves two synchronized acquisition systems, namely an automatic vector network analyzer (VNA) exciting the vibrations and a digital sampling oscilloscope (DSO). The surface vibrations can be monitored independently of reflectivity changes on the scanned surface.
