Quantum-assisted optical interferometers: instrument requirements [PDF]

Optical and Infrared Interferometry and Imaging VII, 2020
It has been recently suggested that optical interferometers may not require a phase-stable optical link between the stations if instead sources of quantum-mechanically entangled pairs could be provided to them, enabling extra-long baselines and benefiting numerous topics in astrophysics and cosmology.

Keck Interferometer nuller instrument performance [PDF]

SPIE Proceedings, 2010
The Keck Interferometer combines the two 10 m Keck telescopes as a long baseline interferometer. It is funded by NASA as a joint development among the Jet Propulsion Laboratory, the W. M. Keck Observatory, and the NASA Exoplanet Science Institute. In February 2008, the 10 um nulling mode began a 32 night observing program with three key science teams ...

The Micro-Precision Interferometer Testbed Instrument Design [PDF]

Symposium - International Astronomical Union, 1994
The Micro-Precision Interferometer Testbed is essentially a space-based Michelson interferometer suspended in a ground-based laboratory. The purpose of the testbed is to serve as a proving ground for technologies needed for future space-based missions requiring low-vibration environments.

The Sydney University Stellar Interferometer -- I. The instrument [PDF]

Monthly Notices of the Royal Astronomical Society, 1999
ABSTRA C T The Sydney University Stellar Interferometer (SUSI) is a new long-baseline optical interferometer located in northern New South Wales, Australia. SUSI has been developed to tackle a range of problems in stellar astrophysics, and its design is based on a successful prototype instrument. In its initial configuration, observations are made with

Highly compact fiber Fabry-Perot interferometer: A new instrument design [PDF]

Review of Scientific Instruments, 2016
This paper presents the design, construction, and characterization of a new optical-fiber-based, low-finesse Fabry-Perot interferometer with a simple cavity formed by two reflecting surfaces (the end of a cleaved optical fiber and a plane, reflecting counter-surface), for the continuous measurement of displacements of several nanometers to several tens

Keck Interferometer: from development phase to facility-class instrument [PDF]

SPIE Proceedings, 2002
The Keck Interferometer is entering a regular limited observational phase. A restricted number of observers are expected to use the instrument over the course of the next few years in a shared-risk capacity. To facilitate this, the W. M. Keck Observatory and the Jet Propulsion Laboratory are following a Handover procedure consisting of a number of ...

Science and instrumentation update from the Palomar testbed interferometer [PDF]

SPIE Proceedings, 2004
The Palomar Testbed Interferometer (PTI) is a near-infrared, long-baseline interferometer located at the Palomar Observatory. PTI obtained first fringes in 1995, and has been in routine scientific operations since 1998. PTI was primarily designed as a technology demonstration experiment for the Keck Interferometer, and has been successful in ...
