Michelson laser interferometer-based vibration noise contribution measurement method for cold atom interferometry gravimeter |
The maximum phase measurement error is about (a) 1.2× 10−1 mrad when ΔL0 is set at the envelope peak point at t = 0 ms; (b) 2× 10−2 mrad when ΔL0 is set at the peak point of envelope at t = 400 ms; (c) 10−4 mrad when ΔL0 is dynamically compensated. The interferometer time in the numerical simulations is 800 ms. |
