  • Three-dimensional temperature probe
    Patent number: 4513749
    Abstract: Two coaxial acoustic beams, one focused and the other unfocused, are used to measure changes in temperature within a localized region in a body. The focal region of the focused beam is located at the area to be measured. Changes in the relative phase angle between the two beams are indicative of changes in acoustic properties occurring at the focal region. Since the two beams have generally the same propagation path outside of the focal region, they will be similarly affected by acoustic variations which occur there, so there will not be any relative phase change between them due to such variations.
