Abstract
A high resolution roll measurement heterodyne interferometer with differential configurations is proposed in this paper. The proposed interferometer is composed of a pair of measurement beams providing environmental noise immunity. The structure is designed and the mathematic model based on Jones' matrix for measuring the roll angle is established. Sensitivity is enhanced dramatically because of the opposite phase shift directions of two signals. An experimental setup is built and an amplification factor of 270 is obtained. Correspondingly, a roll angle resolution of 0.13 arcsec is attained using a phase meter with detecting resolution of 0.01°.
