Abstract: This paper discusses the generation of a novel periodic nonlinear error in homodyne interferometers due to geometric misalignments. These misalignments arise from cumulative assembly errors among the sensor head interior, target mirror, test platform, and… read more here.

Abstract: Homodyne interferometers (HIs) utilize differential signaling to reduce common-mode noise and enhance measurement stability. However, their potential to improve measurement accuracy has not been thoroughly investigated. To address this gap, we reveal two unrecognized mechanisms… read more here.
