im stumped on what type of sensor to use to "scan" objects, and mesure whats inside. (easy explination)

long explanation-

i want to do non destructive testing on rope products that have been altered(on purpose) and check for proper alterations. i need to "scan" the material usually 1/2" diameter lets say and confirm the proper alterations were completed based on a database that is build up of acceptable product.

i am not sure what sensor can be used in this way. maybe ultra sonic on opposing sides and determine a difference in signal strength based on whats inside the ropes jacket. What sensor/s i can setup to measure a difference between like 1 or 2 strands in a certain section?

any help or a point in the right direction would be great. ive search EVERYWHERE. ive seen nothing that is attainable that i can use. possibly terahertz waves? if the sensor can be changed and "dialed in" to figure out the proper signal, thats cool too.

That sounds like a very specialized application. I suspect you will be very lucky if another Forum member knows anything about it.

Computed x-ray tomography.

What type of material? Electromagnetic NDT can find breaks and estimate loss of metallic area in steel wire ropes; it is used to check mine hoist ropes and ferromagnetic cables in other applications.

What proer alterations ?
Splicing ?

What is the material. ?
NDT solutions exist for metal ropes but are highly specialised.

thanks for replies.

i was thinking possibly a ToF image would show some represination of a cross section. kind of like a gpr but small and only looking at a 1/2 diameter
