Acoustical Holography Using Temporally Modulated Optical Holography

  • K. R. Erikson

Abstract

This paper discusses a new technique for obtaining an acoustical hologram using optical holography. Temporal modulation in the form of phase modulation and Doppler upshifting is used in the reference beam of the optical system. This allows recording of the amplitude and phase of sound waves impinging on a mirror interface. The advantages and disadvantages of this system technique are discussed.
