the modulations is coursed by small vibrations in the ground, as the laser and photodiode is alined, and the diode is abit reflective coursing the photon stream to bounce back into the lasers mirror and back to the diode several times. making the smallest vibration or movement of the laser or...
ok, so I've seen the movie
where they aline a HEnE laser with a photodiode to hear the modulations in the photon stream.
i been trying to re-do it, and i just can't get it to work. I am NOT using a HeNe laser, I am using a normal laser from a pen, as i was sure the concept of the laseres...
is someone so kind to explain the statement : quantum physics says : if i stand still you can't find me.
i guess it have something to do with the " you can only know where its going and how fast" atom thingy..
as you can hear, I am not into physics, I am just really really interested in it...
