External Modulation Laser Module Assembly for Improving Measurement Performance of Homodyne Interferometry

An external modulation laser module assembly (EMLMA) is proposed to suppress nonlinear errors in an interferometry system and improve its measurement performance. The EMLMA employs both phase modulation with radio frequency signal and a specific modulation amplitude switching mode, enabling the supp...
