The products of intertidal and super tidal (splash zone) corrosion on steel piles have been characterised at 3 UK sites with contrasting environmental conditions in order to determine corrosion reaction mechanism and if a common mechanism for acceler

In this paper, we present a modal data processing methodology, for reconstructing high resolution surfaces from measured slope data, over rectangular apertures. One of the primary goals is the ability to effectively reconstruct deflectometry measurem

The Thirty Meter Telescope primary mirror consists of 492 diameter segments, with 82 unique prescriptions. This presentation will share the progress of a CGH-assisted Fizeau interferometric testbed, including a proof-of-concept segment measurement.

As part of a study funded by NASA Headquarters, we are developing a Probe-class mission concept called the Cosmic Evolution Through UV Spectroscopy (CETUS). CETUS includes a 1.5-m aperture diameter telescope with a large field-of-view (FOV). CETUS in

CGH Interferometry provides the standard for accurate measurement of transmitted wavefront for large lenses. With multiple patterns on the same substrate, a CGH also enables simultaneous measurements of multiple degrees of freedom used for alignment.

The Thirty Meter Telescope uses a hyperboloidal f/1 primary mirror made from 492 1.4-m segments with 82 different aspheric prescriptions. Each segment will be measured using Fizeau interferometry with spherical reference surface and CGH aspheric corr

A new data processing method based on orthonormal rectangular gradient polynomials is introduced in this work. This methodology is capable of effectively reconstructing surfaces or wavefronts with data obtained from deflectometry systems, especially
