Fiber-optic projected-fringe digital interferometry [PDF]

open access: yes
A phase-stepped projected-fringe interferometer was developed which uses a closed-loop fiber-optic phase-control system to make very accurate surface profile measurements.

Preliminary results on two-dimensional interferometry of HL Tau [PDF]

open access: yes
Preliminary two-dimensional speckle interferometry results of HL Tau were found to be qualitatively similar to those found with one-dimensional slit scanning techniques; results consist of a resolved component (approximately 0.7 arcsec in size) and an ...

Orbits of Binary Stars: from Visual Measures to Speckle Interferometry

open access: yesThe Astronomical Journal
Knowledge of the orbits of visual binary stars has always been one of the fundamentals of astronomy. Based historically on the visual measures, nowadays the orbits rely more (or exclusively) on the accurate speckle data.
