Gray, Malcolm B; Hsu, Magnus; Littler, Ian C M; Warrington, Richard B; Herrmann, Jan; Shaddock, Daniel

Description

We report on an all-digital radio-frequency phasemeter for application in precision length measurements using heterodyne laser interferometry [1]. Our phasemeter has a phase sensitivity of 200 nrad/√Hz at signal frequencies of 0.2 Hz and above. We demon
