Detection of crack in concrete is an important issue as concrete is one of the principal material used in civil infrastructures. Cracks often occur first on the surface of concrete structure under load and provide an indication for further degradation. In this brief, an efficient noncontact method of the detection of such cracks in concrete using a measurement system with a laser displacement sensor...
Cracks often provide an early indication of damage in a structure and must be detected at an early stage. Detecting cracks in complex concrete structures is a challenging task. It is desired that plain as well as non-plain concrete surfaces with complex profiles can be interrogated and cracks on these surfaces as well as hidden under the dielectric coating can be detected. A 3-axis scanning mechanism...
