  • A parametric analysis of the capabilities of undersea acoustic imaging

    Creator:
    Calligan, C. C.
    Abstract:
    The feasibility of utilizing acoustic imaging techniques for improving the undersea viewing capability of small submersibles is investigated. The limiting values of major parameters in acoustic imaging systems are established and graphs which illustrate the parametric relationships are presented. A series of sample calculations illustrate how the graphs can be...

  • Error analysis in scanned holography

    Creator:
    Collins, Heber Dale
    Abstract:
    Acoustic scanned holography is a method of lensless photography which uses sound waves to construct the hologram and light waves to reconstruct the image. The receiving transducer scans a plane area containing the sound field generated or scattered from the objects. In simultaneous source receiver scanning, both the source and...
