An experimental intensity interferometer has been constructed with two searchlight mirrors and tested on Sirius. The correlation observed with the two mirrors close together was found to be in good agreement with that expected theoretically. This result supports the prediction, made in part III of the present series, that the performance of an intensity interferometer should not be significantly affected by atmospheric scintillation. Observations of Sirius were carried out with four different… 

Applications of Intensity Interferometry in Physics and Astronomy

Criteria as to when an intensity interferometer is competitive with a Michelson interferometer are established with the help of a simple example. There do not appear to be any cases in the field of

A Preliminary Measurement of the Angular Diameter of α-Lyrae

IT has been shown by Hanbury Brown and Twiss1–3 that the correlation between the fluctuations in the outputs of two photo-electric detectors illuminated by a source of finite size depends on the

Intensity interferometry with more than two detectors

The original intensity interferometers were instruments built in the 1950s and 1960s by Hanbury Brown and collaborators, achieving milliarcsec resolutions in visible light without optical-quality

Intensity interferometry and the second-order correlation function g (2) in astrophysics

Most observational techniques in astronomy can be understood as exploiting the various forms of the first-order correlation function g (1) . As demonstrated by the Narrabri stellar intensity

The Angular Diameter and Fundamental Parameters of Sirius A

The Sydney University Stellar Interferometer (SUSI) has been used to make a new determination of the angular diameter of Sirius A. The observations were made at an effective wavelength of 694.1 nm

Sirius: a prototype astronomical intensity interferometer using avalanche photodiodes in linear mode

Optical intensity interferometry, developed in the 1950s, is a simple and inexpensive method for achieving angular resolutions on microarcsecond scales. Its low sensitivity has limited intensity

Feasibility of observing Hanbury Brown and Twiss phase

The interferometers of Hanbury Brown and collaborators in the 1950s and 1960s, and their modern descendants now being developed (intensity interferometers) measure the spatial power spectrum of the

Optical Multi-Channel Intensity Interferometry - or: How To Resolve O-Stars in the Magellanic Clouds

Intensity interferometry, based on the Hanbury Brown-Twiss effect, is a simple and inexpensive method for optical interferometry at microarcsecond angular resolutions; its use in astronomy was

Two-beam interferometric spectroscopy

Spectroscopy by two-beam interferometry is compared with conventional techniques and it is shown that considerable advantages may be expected in some measurements from the use of interferometers. The
