Eddy current testing (ECT) is a nondestructive testing (NDT) technique used to detect surface and sub-surface defects using principles of electromagnetic induction.

Nondestructive Testing (NDT) based on laser technology has witnessed incremental acceptance in the NDT industry since the early 1990’s with shearography and holography interferometry as the most widely recognized techniques based on this technology.

Although initially developed as a method for detecting defects in structures in order to safeguard against catastrophic failures, ultrasonic non-destructive testing (NDT) has evolved immensely to a technique considered the mainstay for the NDT industry.

The market for coordinate measuring machines (CMMs) is mature and, as such, experiencing low revenue growth rates.
