Most sensitive: At its most sensitive state, LIGO will be able to detect a change in distance between its mirrors 1/10,000th the width of a proton! This is equivalent to measuring the distance to the nearest star (some 4.2 light years) to an accuracy smaller than the width of a human hair!
You need to be a lot more specific. Are these two objects next to each other? How big are these object? What part of the object is the measurement to be taken at? Are they static? Are they on the ground? Is there clear line of sight to the objects? Are you willing to spend a few million dollars to make the measurement? Is this just a wild thought thrown out or do you have a specific application in mind?Do you think it is possible to measure if an object is 1 milimetre closer than other; from 200+ Km away ?
From what I learnt from someone trained by Wild, measurements could be done in situ, so to speak, and then, the resulting values, sent to you. Othertwise, TOF should count.Do you think it is possible to measure if an object is 1 milimetre closer than other; from 200+ Km away ?
That's about 1 part in 10^9.Do you think it is possible to measure if an object is 1 milimetre closer than other; from 200+ Km away ?
