The Gravitational Redshift in a Local Freely-Falling Frame: A New Null Test of the Equivalence Principle
We consider the gravitational redshift effect measured by an observer in a local freely-falling frame in the gravitational field of a massive body.

Progress in four-beam nulling: results from the Terrestrial Planet Finder planet detection testbed
The Terrestrial Planet Finder Interferometer (TPF-I) is a large space telescope consisting of four 4 meter diameter telescopes flying in formation in space together with a fifth beam combiner spacecraft.

Stitching of near-nulled subaperture measurements
A metrology system for measuring aspheric test objects by subaperture stitching. A wavefront-measuring gauge having a limited capture range of wavefront shapes collects partially overlapping subaperture measurements over the test object. A variable optical aberrator reshapes the measurement wavefront with between a limited number of the measurements to maintain the measurement wavefront within the capture range of the wavefront-measuring gauge. Various error compensators are incorporated into a stitching operation to manage residual errors associated with the use of the variable optical aberrator.
