Astronomical Optical Interferometry.

Literature Review, Bob Tubbs, April 1997.

An historical account of the development of Optical Interferometry and discussion of the principles involved. Written by an undergraduate for an undergraduate audience.

Areas covered explicitly

* Michelson's early work
* The development of radio interferometry
* Simple synthetic aperture imaging
* Closure phase
* Modern optical interferometers

Areas not covered in depth

* Intensity interferometers
* The use of closure relations in aperture synthesis imaging

Accounts for approximately three weeks' work as part of the Natural Sciences Tripos undergraduate degree at Cambridge University.

My Ph.D. thesis on Lucky Exposures / Video Astronomy.
Tracking and Characterising Atmospheric Phase Fluctuations at COAST.

Part III Project, Bob Tubbs, May 1998.

Techniques for studying the properties of interference fringes formed in Astronomical Optical Interferometers.

Areas covered explicitly

* Tracking phase changes in interference fringes
* Measuring the position of the fringe envelope
* The effect of optical dispersion on closure phase measurements
* Suggested new techniques for closure phase measurement

Accounts for approximately six weeks' work as part of the Natural Sciences Tripos undergraduate degree at Cambridge University.
