Abstract

Autonomous non-destructive inspection equipment provides automatic and/or continuous inspection and evaluation of a material under inspection. The inspection equipment comprises at least one detection sensor and at least one detection sensor interface for a computer. The signals are communicated from the sensor to the computer. The signals are then conditioned and evaluated according to knowledge already inputted into the computer. The computer iterations are processed until an acceptable conclusion is made regarding the type of imperfection that is detected.
