A `hard' X-ray LLL interferometer is tested for experimental investigations. The interferometer has both a base and a `ceiling', which are rigidly connected through columns. As a result, the ...

What happens when a precision Zygo laser interferometer is dropped from a forklift? Will it survive? Watch the video to see what happens! While dropping a precision interferometer isn't part of our ...

Abstract: The authors have rearranged an optimal method for signal processing of interferometric measurements, based on the angle-of-arrival estimation approach, and have analyzed errors of estimating ...

Abstract: In this paper, a structure depending on a birefringent interferometer (BFI) cascaded with polarization-maintaining FBG (PM-FBG) is proposed and experimentally demonstrated. Two different ...

High accuracy optical surface measurements are usually achieved by utilizing interferometric methods. Under null testing conditions resolutions in the single digit nanometer range are gathered for ...

Optical Surfaces Ltd has developed a 600mm Fizeau interferometer enabling it to now offer quality testing of flats in a single aperture up to 600mm in diameter. This is a capability that only a few ...

An experiment by a team of researchers led from the University of Waterloo's Institute for Quantum Computing shows, for the first time, that a wave property of neutrons, Orbital Angular Momentum, can ...
