Rubidium vapor holography for noncontact adaptive detection of ultrasound

Abstract

We describe an adaptive interferometer based on rubidium vapor, which combines a good signal-to-noise ratio with a high cutoff frequency of $\sim 1\text{\hspace{0.17em} MHz}$. These features can be useful for optical detection of ultrasound generated in diffusely scattering objects in the presence of strong environmentally produced vibrations.
