1. A transducer structure, comprising:

  • at least one metal or semiconducting film in which a part of a pump light pulse is absorbed to generate a sound pulse; and

    at least one dielectric film, where the thicknesses and optical properties of the at least one metal or semiconducting film and the at least one dielectric film are selected so that a returning sound pulse results in a measurable change in the optical reflectivity and/or some other optical characteristic of the transducer structure.
