How do you distinguish a heart of a human and the heart of a rat with at that distance and that noise level?
I've used https://en.wikipedia.org/wiki/Lock-in_amplifier https://en.wikipedia.org/wiki/Lock-in_amplifier and in ideal conditions you get a 10^6 amplification, when you send a very clean signal and measure how it bounce.
My expert opinion is that 10^18 is im-facking-possible.
