Heterodyne 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 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 کاملA dual-heterodyne laser interferometer for simultaneous measurement of linear and angular displacements.
Picometer laser interferometry is an essential tool for ultra-precision measurements in frontier scientific research and advanced manufacturing. In this paper, we present a dual-heterodyne laser interferometer for simultaneously measuring linear and angular displacements with resolutions of picometer and nanoradian, respectively. The phase measurement method is based on cross-correlation analys...
متن کاملImproved common-path optical heterodyne interferometer for measuring small optical rotation angle of chiral medium
An improved common-path optical heterodyne interferometry for measuring small optical rotation angle of chiral liquid is presented. The optical rotation angle can be determined by the phase difference between the test and reference signals. By means of inserting a phase retarder behind the test sample, the measuring resolution of optical rotation angle is greatly enhanced. The theoretical predi...
متن کاملHigh-resolution, high-speed, low data age uncertainty, heterodyne displacement measuring interferometer electronics
An advanced displacement measuring interferometer system has been developed to satisfy the needs of semiconductor manufacturing and lithography. The system electronics provides a position resolution of 0.31 nm at velocities up to 2.1 m s−1 when the system is used with a double-pass interferometer. Output data rates up to 107 samples per second are available. The data age, which is the delay fro...
