A wide variety of applications exist in science and industry for BAT® transducers. Most remain largely unexplored since the field is relatively new. The examples assembled here serve to show the general capabilities of BAT® technologies in actual measurements so that you might better judge what is possible for any particular application of interest.  


 

 
 

 

Index A: In-Air & Reflection Measurements (in these measurements ultrasound does not cross any gas/solid or gas/liquid interfaces)

  1. pulse-echo surface imaging of solids
    1. using a focussed reflecting lens
    2. using a micromachined Fresnel zone-plate
  2. tomographic imaging in gases
    1. of flow fields
    2. of temperature fields
  3. communication with animals & insects
    1. recording the songs of katydids
    2. recording and mimicking the cries of bats

 

Index B: Non-contact NDT Measurements (in these measurements, ultrasound is generated and received in solid or liquid materials through an intervening air- or gas-layer)

  1. thru-transmission C-scans of solid material
    1. 16-ply CFRP plate
    2. 50-ply CFRP plate
    3. bond-line thickness measurement in aluminum lap-joints
    4. thermoplastic composite plate
    5. carbon-fibre composite patch on aluminum
    6. Kevlar-fibre composite panel
    7. Nomex-CFRP panel
  2. single-sided C-scans of solid material
    1. bonded riveted aluminum lap-joint
