title = "Fine correction of nonlinearity in homodyne interferometry",
abstract = "In a typical homodyne interferometer with 4-channel detectors, the nonlinearity resulting from beam power drifting couldn't be thoroughly suppressed by Heydemann correction. This study presents an analysis of the nonlinearity resulting from beam power drifting. From a theoretical approach, the nonlinearity model before and after conventional Heydemann correction is built. And a fine correction method involving Heydemann correction with partial data is introduced. The experimental results indicate that, the proposed method suppresses the nonlinearity in a homodyne interferometer to 0.18 nm, which would be 1.49 nm with conventional Heydemann correction.",
