Ghost Beam Suppression in Deep Frequency Modulation Interferometry for Compact On-Axis Optical Heads

Ghost Beam Suppression in Deep Frequency Modulation Interferometry for Compact On-Axis Optical Heads

We present a compact optical head design for wide-range and low noise displacement sensing using deep frequency modulation interferometry (DFMI). The on-axis beam topology is realised in a quasi-monolithic component and relies on cube beamsplitters and beam transmission through perpendicular surface...
