Fig. 7: Dependence of optimum cavity length and acceleration sensitivity on source momentum width.

From: Theoretical investigation of an atomic Fabry Perot interferometer based acceleration sensor for microgravity environments

Fig. 7

a Plot showing the optimum value of the cavity length (which gives maximum FC) as a function of the momentum width of the BEC source. The optimum cavity length decreases with increasing momentum width. b Minimum detectable change in acceleration, δa decreases with decreasing momentum width of the BEC source. Hence acceleration sensitivity improves with decreasing momentum width. Here, k0 = 2π/(780 nm).
