A digital phasemeter for precision length measurements

Gray, Malcolm B; McRae, Terry G; Hsu, Magnus; Herrmann, Jan; Shaddock, Daniel

Description

We report on a digital phasemeter for application in precision length measurement using laser interferometry. Our interferometer demonstrates a length sensitivity of 0.5 pm/√Hz above 5 Hz, and a cyclic error of better than 50 pm.
