Journal ArticleDOI
Development of a compact, fiber-coupled, six degree-of-freedom measurement system for precision linear stage metrology
TL;DR: A compact, fiber-coupled, six degree-of-freedom measurement system which enables fast, accurate calibration, and error mapping of precision linear stages is presented and has the advantages of simplicity, compactness, and relatively low cost.
Journal ArticleDOI
Robust high-dynamic-range optical roll sensing.
TL;DR: This sensor has the highest reported dynamic range for optical roll sensing and the working principle is presented, and a 43° usable working range with 0.002° resolution is experimentally validated.
Journal ArticleDOI
Beam geometry, alignment, and wavefront aberration effects on interferometric differential wavefront sensing
TL;DR: In this article, an analytical model is presented to predict the scaling of differential phase signals based on fundamental Gaussian beams, where the angular change is measured using a weighted phase average between symmetrically adjacent quadrant photodiode pairs.
Journal ArticleDOI
Absolute air refractive index measurement and tracking based on variable length vacuum cell
TL;DR: In this article, a modified Wu-type heterodyne interferometer with a variable length vacuum cell is presented, which can be used for real-time refractive index compensation.
