I finished Dan Brown's new book and I had the following thought.

I don't consider this a spoiler, but you might, so don't read further if you are concerned.


At one point in the book, there was some really cool technology that I "thought of" years ago and I was wondering if anyone knew if it was real.

It was an ultra-sophisticated IR system that could read very small changes in temperature, so that a spot where someone had rested their hand for a few moments was visible minutes later.

I had no idea how to mechanize it, but theoretically this spot should always be a little hotter than its surroundings (asymptotically approaching the surrounding temperature) until something happens to raise the surroundings' temperature. After that, it's only measuring (and filtering) the temperature.

So, does anyone know if this technology is available and portable (goggles in the book)?

Thermal imaging cameras can do this, but there is a point at which the handprint is unreadable. Mostly due to the dissipation of the heat through the surrounding conductive materials, including ambient air. I don't know if thermal imaging cameras can be made as small as what you said, however.

To be clear, they weren't reading the print, I think they recognized it as a handprint, but not much more detail than that.

Haven't read the book, but...it's all about signal to noise ratio. In anything above absolute zero, there will be some thermal noise, and as things get hotter the noise increases. If I rest my hand on a wall, yes in theory that patch will be slightly warmer until other heat sources are applied to the wall, but very quickly the warmth from my hand will be drowned out by the ambient noise.

By unreadable I meant undetectable. I didn't think they could read the actual prints for ID.

Hopefully they can fix discover plot cohesion for the next... well, any work with Dan Brown's name attached to it

Dan Brown confuses plot with controversy.
