Abstract: Absolute testing is a key technique for achieving nanoscale measurements in Fizeau interferometry. Traditional methods use Zernike polynomials to fit the ...
Ten years ago, astronomers made an epic discovery with the Laser Interferometer Gravitational-Wave Observatory. Cosmology hasn’t been the same since, and it might not stay that way much longer. Out ...
Interferometers, devices that can modulate aspects of light, play the important role of modulating and switching light signals in fiber-optic communications networks and are frequently used for gas ...
Abstract: In this paper, a Fizeau interferometer is used to evaluate the out-of-flatness error and the pitch deviation of a reflective-type linear scale. The out-of ...
