A modified Mach Zehnder interferometer system has been developed to measure surface motion with 4 ns temporal resolution and 0.2 nm displacement sensitivity. We discuss its use to measure the optical properties of homogeneous turbid media and image heterogeneous volumes to depths of 1 cm with ~200 micrometer resolution.
