  2. Side-scan sonar - Wikipedia

    en.wikipedia.org/wiki/Side-scan_sonar

    The first commercial side-scan system was the Kelvin Hughes "Transit Sonar", a converted echo-sounder with a single-channel, pole-mounted, fan-beam transducer introduced around 1960. In 1963 Dr. Harold Edgerton, Edward Curley, and John Yules used a conical-beam 12 kHz side-scan sonar to find the sunken Vineyard Lightship in Buzzards Bay ...

    Ultrasonic transducer. A curvilinear array ultrasonic transducer for use in medical ultrasonography. Inside construction of a Philips C5-2 128 element curved array ultrasound sensor. Ultrasonic transducers and ultrasonic sensors are devices that generate or sense ultrasound energy. They can be divided into three broad categories: transmitters ...

  4. Orthomode transducer - Wikipedia

    en.wikipedia.org/wiki/Orthomode_transducer

    An orthomode transducer ( OMT) is a waveguide component that is commonly referred to as a polarisation duplexer. Orthomode is a contraction of orthogonal mode. Orthomode transducers serve either to combine or to separate two orthogonally polarized microwave signal paths. [1] One of the paths forms the uplink, which is transmitted over the same ...

    en.wikipedia.org/wiki/Scanning_acoustic_microscope

    A scanning acoustic microscope ( SAM) is a device which uses focused sound to investigate, measure, or image an object (a process called scanning acoustic tomography). It is commonly used in failure analysis and non-destructive evaluation. It also has applications in biological and medical research. The semiconductor industry has found the SAM ...

    en.wikipedia.org/wiki/Medical_ultrasound

    Medical ultrasound includes diagnostic techniques (mainly imaging techniques) using ultrasound, as well as therapeutic applications of ultrasound. In diagnosis, it is used to create an image of internal body structures such as tendons, muscles, joints, blood vessels, and internal organs, to measure some characteristics (e.g. distances and velocities) or to generate an informative audible sound.

    Collimator used to collimate gamma rays (red arrows) in a gamma camera. Single-photon emission computed tomography ( SPECT, or less commonly, SPET) is a nuclear medicine tomographic imaging technique using gamma rays. [1] It is very similar to conventional nuclear medicine planar imaging using a gamma camera (that is, scintigraphy ), [2] but is ...

  9. Multibeam echosounder - Wikipedia

    en.wikipedia.org/wiki/Multibeam_echosounder

    Multibeam echosounder. Multibeam sonar is used to map the ocean floor. A multibeam echosounder ( MBES) is a type of sonar that is used to map the seabed. It emits acoustic waves in a fan shape beneath its transceiver. The time it takes for the sound waves to reflect off the seabed and return to the receiver is used to calculate the water depth.
