(+) Been through that. Won't work. Still a hard nut. |
|
|
Xray each nut to detect the hard spots. Use constructive interference of two ultrasonic speakers to break those up. |
|
|
Would there be sufficient difference in density for X-rays to discriminate ? |
|
|
Ultrasound might work; what's needed is an energy input that is preferentially absorbed by regions of higher density/rigidity. |
|
|
Phase-contrast X-ray should work. |
|
|
Good idea. Placing the nut on a rotating stage would allow a sort of CT image to be produced, enhancing targeting. |
|
|
Better to mount the CT scanning apparatus on a large mobile gantry, so as to allow full analasys without disturbing the position or orientation of the nut? |
