The Palomar Testbed Interferometer
The Palomar Testbed Interferometer (PTI) is a long-baseline infrared interferometer located at Palomar Observatory, California. It was built as a testbed for interferometric techniques applicable to the Keck Interferometer. First fringes were obtained in July 1995. PTI implements a dual-star architecture, tracking two stars simultaneously for phase referencing and narrow-angle astrometry. The t...

متن کاملThe NIST Length Scale Interferometer
National Institute of Standards and Technology, Gaithersburg, MD 20899-0001 The National Institute of Standards and Technology (NIST) interferometer for measuring graduated length scales has been in use since 1965. It was developed in response to the redefinition of the meter in 1960 from the prototype platinum-iridium bar to the wavelength of light. The history of the interferometer is recalle...
متن کاملThe quantum-optical Josephson interferometer
The photon-blockade effect, where nonlinearities at the single-photon level alter the quantum statistics of light emitted from a cavity1, has been observed in cavity quantum electrodynamics experiments with atomic2,3 and solid-state systems4–8. Motivated by the success of single-cavity quantum electrodynamics experiments, the focus has recently shifted to the exploration of the rich physics pro...
متن کاملThe Einstein polarization interferometer for cosmology (EPIC) and the millimeter-wave bolometric interferometer (MBI)
We provide an overview of a mission concept study underway for the Einstein Inflation Probe (EIP). Our study investigates the advantages and tradeoffs of using an interferometer (EPIC) for the mission. We also report on the status of the millimeter-wave bolometric interferometer (MBI), a ground-based pathfinder optimized for degree-scale CMB polarization measurements at 90 GHz. 2006 Elsevier B....
