Physical Optics Analysis of a Fiber-Delivered Displacement Interferometer
Optical interferometry has been used for over a century for precision metrology. Advances in interferometry, such as the inclusion of a laser source, have increased the precision of such interferometers. In this thesis, we examine a fiber-fed, heterodyne, spatially separated, differential wavefront interferometer. The combination of technology in this interferometer can allow easier and more ro...
متن کاملHeterodyne displacement interferometer, insensitive for input polarization.
Periodic nonlinearity (PNL) in displacement interferometers is a systematic error source that limits measurement accuracy. The PNL of coaxial heterodyne interferometers is highly influenced by the polarization state and orientation of the source frequencies. In this Letter, we investigate this error source and discuss two interferometer designs, designed at TU Delft, that showed very low levels...
متن کاملValidation of separated source frequency delivery for a fiber-coupled heterodyne displacement interferometer.
The use of optical fibers presents several advantages with respect to free-space optical transport regarding source-frequency delivery to individual heterodyne interferometers. Unfortunately, fiber delivery to individual coaxial heterodyne interferometers leads to an increase of (periodic) nonlinearity in the measurement, because transporting coaxial frequencies through one optical fiber leads ...
متن کاملError Analysis, Design and Modeling of an Improved Heterodyne Nano-Displacement Interferometer
A new heterodyne nano-displacement with error reduction is presented. The main errors affecting the displacement accuracy of the nano-displacement measurement system including intermodulation distortion error, cross-talk error, cross-polarization error and phase detection error are calculated. In the designed system, a He-Ne laser having three-longitudinal-mode is considered as the stabiliz...
متن کاملNonlinearity in a fiber-optic coupled heterodyne interferometer
A high-accuracy (nonlinearity < 2nm) fiber-optic coupled displacement heterodyne measuring Michelson interferometer is developed. The primary limitation of accuracy encountered with this fiber-optic coupled heterodyne interferometer is the optical mixing arising from the imperfection of fiber-optic coupling system. The optical mixing results in the nonlinearity (first order and second order err...
