|Invasive non contact 3d mapping
is the process of looking inside something without physically penetrating the
surface of that object or material.
This process requires the use of an array to generate the 3d view of the
Capacitive and electric fields can penetrate non metallic materials
Non-contact because transmit and sense electrodes do not require
physical contact with the surface of the material to transmit electric field
onto and into the material.
Fields produced by the sensor are transmitted through the material and
received by sensors in the array. Changes in material consistency or objects
embedded in the material disturb the electric field, which is detected by sense
Taking many views of sections of the material using arrays, allows a picture
to be built up of the internal topography of the material.
Detecting corrosion on inner surfaces of containers.
