The Palomar Testbed Interferometer is a near-IR, long-baseline stellar interferometer located at Palomar Observatory in north San Diego County. It was built by Caltech/JPL and is intended to serve as a testbed for developing interferometric techniques to be used at the Keck Interferometer. It began operations in 1995 and acheieved routine operations in 1998, producing more than 35 refereed papers in a variety of scientific journals covering topics from high precision astrometry to stellar masses, stellar diameters and shapes.

PTI is notable for being equipped with a "dual-star" system, making it possible to simultaneously observe pairs of stars; this cancels some of the effects of atmospheric seeing and makes very high precision measurements possible. The word seeing can mean more than one thing: In common usage, the word means visual perception In astronomy, seeing is a technical term related to the blurring effects of air turbulence in the atmosphere In the occult seeing refers to the sight or the ability to see auras or...

Palomar Observatory is a privately-owned observatory located in San Diego County, California, 90 miles (145 km) southeast of Mount Wilson Observatory, on Palomar Mountain.
The word palomar is from the Spanish language, dating back from the time of Spanish California, and means pigeon house (in the same sense as henhouse).
The Palomar Observatory Sky Survey (POSS), sponsored by the National Geographic institute, was completed in 1958 (The first plates were shot in November 1948 to and the last in April 1958).
