Tomographic reconstruction of picosecond acoustic strain pulses using automated angle-scan probing with visible light

Tomographic reconstruction of picosecond acoustic strain pulses using automated angle-scan probing with visible light

By means of an ultrafast optical technique, picosecond acoustic strain pulses in a transparent medium are tomographically visualized at GHz frequencies. The strain distribution in BK7 glass is reconstructed from time-domain reflectivity changes of 415-nm probe light as a function of the optical inci...
