EyeCon is based on the ultrasonic pitch-catch method and uses an antenna composed of an array of dry point contact (DPC) transducers, which emit shear waves into the concrete. The 4 by 6 transducer array is under computer control and the recorded data are analyzed to create 2-D images of the reflecting interfaces within the cross sections below the antenna. The series of 2-D images obtained from a 2- dimensional surface scan of the test object are transferred to a computer with IntroView imaging software. The software can assemble the 2-D slices into a complete 3-D image of the test object. The 3-D image can then be manipulated for interpretation of test results.

As a pulse-echo tester:

• Thickness measurement
• Detection of voids and honeycombing in concrete elements
• Detection of voids in grouted tendon ducts
• Detection of poor-quality bond in overlays and repairs
• Detection of delaminations
• Detection of lack of support behind tunnel linings and below slabs on grade.

As an Ultrasonic Pulse Velocity tester:

• Evaluating the uniformity of concrete within a structural member
• Inferring the presence voids and cracks
• Estimating the depth of surface-opening cracks
• Estimating severity of deterioration 
• Estimating depth of fire damaged concrete
• Evaluating effectiveness of crack repairs
• Identifying anomalous regions for invasive sampling with drilled cores
• Estimating early-age strength (with project specific correlation)
