Re: New Scanner Tech Watch Thread

TeraHertz 3D closed book scanner.

So ironic.. I was thinking of this last year.

Re: New Scanner Tech Watch Thread

Yeah those videos would be by me. The scanner is nice, but the software has some growing pains to go through. The software development looks stalled while they focus on assembly and shipping. They were making two models, a black and a white. The black models were produced first and they were getting...

Re: Some (crappy) videos of Google's linear book scanner

Why does that remind me of a Battlestar Galactica Launch Tube?

Re: A cheap 3D Volume to Page Scanner?

I found a $300 XY robot that has a generic mounting carriage. The Youtube videos seem to indicate it has the resolution that would be required to digitize some pretty small fonts. The idea would be to make this "atomic" depth sensor to ride the carriage back and forth, stepping it along and letting ...

Re: A cheap 3D Volume to Page Scanner?

I noticed a really cool description of PiN diodes being used as X-Ray, Gamma and Alpha, Beta particle detectors. I also read of a recent Kickstart project that used that effect to build a sensor as an add-on component for arduino or adafruit projects. They have a side business for robot parts and ma...

Re: A cheap 3D Volume to Page Scanner?

Well.. I wasn't exactly envisoning one of those 'Eye of the Storm' or 'Tesla coils' flinging bolts of lightning. The eV would be high, but the coulombs or amperage would be very low.. it would be as subtle as a spectrographic analysis with X-Y and depth information. I do see what you mean however pr...

A cheap 3D Volume to Page Scanner?

Has anyone considered using Particle Beams to scan a closed book layer by layer? I was thinking of using a Beta source, then amplifying its penetrating power and directionality with a rising and collapsing electromagnetic field. It would be tuned to both reject and re-enforce the penetrating depth s...
