  2. Ultrasonic thickness measurement - Wikipedia

    en.wikipedia.org/wiki/Ultrasonic_Thickness...

    An ultrasonic thickness gauge is a measuring instrument for the non-destructive investigation of a material's thickness using ultrasonic waves. The usage of an ultrasonic thickness gauge for non-destructive testing to check material properties such as thickness measurement, is regular in all areas of industrial measurements.

  3. Ultrasonic testing - Wikipedia

    en.wikipedia.org/wiki/Ultrasonic_testing

    A common example is ultrasonic thickness measurement, which tests the thickness of the test object, for example, to monitor pipework corrosion and erosion. Ultrasonic testing is extensively used to detect flaws in welds.

  4. Terahertz nondestructive evaluation - Wikipedia

    en.wikipedia.org/wiki/Terahertz_nondestructive...

    There are millions of dollars of ultrasonic equipment in the field and on the market that are used as thickness gauges and density meters. When terahertz nondestructive evaluation is fully commercialized into a more portable form, and becomes less expensive it will be able to replace the ultrasonic instruments for structural plastic , ceramic ...

    en.wikipedia.org/wiki/Phased_array_ultrasonics

    Animation showing the principle of an ultrasonic scanner used in medical ultrasonic imaging. It consists of a beamforming oscillator (TX) that produces an electronic signal consisting of pulses of sine waves oscillating at an ultrasonic frequency, which is applied to an array of ultrasonic transducers (T) in contact with the skin surface that convert the electric signal into ultrasonic waves ...

  6. Ultrasound - Wikipedia

    en.wikipedia.org/wiki/Ultrasound

    Ultrasonic sensors are also used to detect intruders; the ultrasound can cover a wide area from a single point. The flow in pipes or open channels can be measured by ultrasonic flowmeters, which measure the average velocity of flowing liquid. In rheology, an acoustic rheometer relies on the principle of ultrasound.

  9. Laser ultrasonics - Wikipedia

    en.wikipedia.org/wiki/Laser_ultrasonics

    Laser-ultrasonics uses lasers to generate and detect ultrasonic waves. [1] It is a non-contact technique used to measure materials thickness, detect flaws and carry out materials characterization. The basic components of a laser-ultrasonic system are a generation laser, a detection laser and a detector.
