Palomar Testbed Interferometer (PTI). The PTI is used to measure the diameters of stars,the size of the emissions surrounding young stars,and binary star orbits. A network of beam pipes are seen between instrument houses,each containing a small telescope,of which there are three in total. The resolving power of all three telescopes are combined to produce a higher resolution that is the equivalent of a 110-metre telescope. The PTI is located at the Palomar Mountain Observatory,which sits at an elevation of 1867 metres within the Palomar mountain range in California,USA | |
